PG’s own Nikos Arvanitis takes the crying out of wah-wah with this simple guide to seven techniques for the venerable device.
Using a JAM Pedals Whacko, a Tele, and a Fender Deluxe, he starts by explaining the wah's basic function as a filter: heel down accents low tones, heel up accentuates highs. Simple enough for the wah novice. Then, he demos how to use the pedal as a textural instrument, while playing hammer-ons and pull-offs. (Hint: sweep the pedal slowly!) Next up is the classic whacka-whacka that gives this JAM pedal its name. This one requires a good sense of rhythm, so pull out the metronome if you're uncertain. Emphasizing single notes and bends comes next. It's a way to lend your playing a vowel-like quality. Jazz chord wah-wah? Sure—especially with an ample helping of reverb. (Think Skip Pitts’ brilliant work on “Theme from Shaft.”)
To use the wah's EQ purely as a filter, find a setting where you dig the tone, set it, and wail. This is something bluesman Albert Collins did on some of his earlier recordings, to get his frosty tone. For big, distorted chords, move the wah slowly through its range while they sustain for an arresting new flavor in your sound. And if you don't have a wah handy, consider using your guitar’s tone knob to approximate the effect. Finally, remember not to overuse the wah. You want to preserve the element of surprises for your listeners. Want to continue your wah-ucation? Check out our Rig Rundown with Steve Vai and Tom Morello, or our feature on bluesman Herman Hitson. Of course, you can do your homework by listening to recordings, too. Start with Jimi Hendrix ("Voodoo Chile") and work your way up through Kirk Hammett ("No Remorse,” “Enter Sandman"), and that’s just the Hs.
When Louis Cato received this Univox LP-style as a gift in high school, it needed some major TLC. A few years later, it got some practical upgrades and now makes regular appearances with Cato on The Late Show.
The self-described “utility knife” played drums with John Scofield and Marcus Miller and spent time in the studio with Q-Tip before landing on Stephen Colbert’s show as a multi-instrumentalist member of the house band. Now, he’s taken over as the show’s guitar-wielding bandleader and is making his mark.
It’s a classic old-school-show-biz move: Bring out the band, introduce them one by one, and build up the song to its explosive beginning. It’s fun, dramatic, audiences love it, and that’s how every The Late Show with Stephen Colbert taping starts.
By this time, us audience members have been sitting in Manhattan’s chilly Ed Sullivan Theater for about 90 minutes. We’ve gotten our seats, had a bathroom break after getting settled, and had some fun with warm-up comic Paul Mecurio. The first musician summoned by announcer Jen Spyra is drummer Joe Saylor. Wearing his trademark cowboy hat, he jogs out, gets behind the kit, and kicks off an up-tempo second-line groove. Next comes upright bassist Endea Owens and percussionist Nêgah Santos. The band’s trumpeter, Jon Lampley, is introduced, and he’s brought along his bandmates in the Huntertones as guests, so saxophonist Dan White and trombonist Chris Ott come out as well.
Louis Cato feat. Stay Human "Look Within"
The multitalented Louis Cato leads the Stay Human band through a special rooftop performance of his song “Look Within,” from his album, Starting Now.
The audience is now on its feet, the band’s pocket is thick, and the energy is building. When bandleader Louis Cato charges onstage, he reaches his mic on the bandstand and shouts, “I feel good today!” with explosive enthusiasm and a big grin, and the band launches into Jon Batiste’s “I’m from Kenner.” Cato sings the catchy and gleeful refrain: “I feel good, I feel free, I feel fine just being me / I feel good today.” And the audience is feeling the love. Almost everyone is bouncing and clapping along.
A couple minutes in, when it seems like the song has reached its super-positive-vibe, high-energy climax, Cato shouts into his mic, “How do you feel today, Stephen?” And with that, Colbert comes running out from the middle of the set. Cato leaps from the bandstand toward the host as the crowd explodes. The two grab hold of each other and attempt to spin around, but the bandleader, holding his black-sparkle Tuttle T-style, loses his grip and goes sliding across the shiny stage. There’s a second where both are comically stunned—Kevin McCallister Home Alone-expressions on both of their faces—but Cato quickly jumps to his feet, both he and his guitar unharmed, and runs back to the bandstand, where he keeps the song moving along with his bandmates, who haven’t missed a beat.
All this excitement isn’t even for the TV audience! Colbert is coming out for the un-televised pre-show Q&A. In a few minutes, they’ll do a new taped intro that looks more like what we see every night. But they’ve gotten the crowd energized, and we need to keep it up. They need our energy to do their jobs.

As Cato sees it, that’s what his role as bandleader is all about: keeping the audience engaged and amplifying the drama and action of the show. “That translates to the energy that the viewers get at home,” he explains. “For all of us here, we’re able to feed off that energy and do the best possible show that we all can.”
Colbert agrees with that job description and adds that the bandleader himself has the same contagious effect on his players. “Louis is an extraordinarily gifted multi-instrumentalist,” he says, “whose spirit of creativity and collaboration not only elevates everything the band does musically but inspires me to be better at my job.” He adds, “I’m so happy to call him my friend.”
Beyond his infectious energy and charisma, there are a lot of ways Cato keeps the Late Show Band invigorated from night to night. For one, he keeps the music fresh by tackling a new cover song every day. That doesn’t mean running down rote note-for-note charts. Cato and the band take a reconstructionist approach that fans of his work—whether from his collaborations with artists such as the Huntertones, Scary Pockets, or Vulfpeck, or from his regular Instagram cover-song posts—will recognize.
“Louis is an extraordinarily gifted multi-instrumentalist whose spirit of creativity and collaboration not only elevates everything the band does musically but inspires me to be better at my job.”—Stephen Colbert
On this evening, the band runs through a host of multi-genre reinterpretations during the two-episode taping, including a slow-burning and soulful “Smokestack Lightning,” a New Orleans-style “Down by the Riverside,” and a fingerpicked, acoustic-led take of Joni Mitchell’s “Free Man in Paris” that gets Colbert lip syncing along off camera. On a horn-driven arrangement of Stevie Wonder’s “Love’s in Need of Love Today,” there’s a re-worked bridge that creates a generous feature spot for the guest horn players.
Every arrangement brings a new and unique perspective to a classic track, to ensure the band is “not just a wedding band doing a cover of a song on the radio.” Cato adds, “We’re arranging it and making it our own—because that’s the sonic fingerprint of our show.”

A Lifelong Path
Listening to the story of Cato’s musical life, it seems that this job—with its demand for a blend of careful strategizing and on-the-fly creative thinking, as well as effortless instrumental skills and charismatic showmanship—is what he’s been training for since the beginning.
On the morning of the taping I attended, I meet Cato in his dressing room. Painted with sky-blue walls and a cloud mural on the ceiling, it’s a comfortable place to hang. The bandleader is wearing slim-fit floral pants, a hoodie over a black T-shirt, and a long necklace. He sits across from me on his couch, next to a guitar stand that holds a few instruments—including his Tuttle, a Jesse Stern-built baritone acoustic, and his Univox LP-style—and a ’65 Deluxe Reverb reissue with a Universal Audio Dream ’65 pedal plugged into it.
“There’s not a time in my brain when I was not making music in some way or form,” Cato says. His mother, a pianist in the Church of God in Christ, bought her son a Diamond drum kit that he recalls having paper heads when he was just 2 years old, and she started teaching the toddler to accompany her. “I marvel at my mom,” he laughs. “Like, who buys their 2-year-old a drum kit?” After playing those drums every day for a year, he started accompanying her at services.
The family moved around a lot. Cato’s father was in the Air Force, and Louis was born on a base in Lisbon, Portugal, before moving to Dayton, Ohio. Not long after he started playing in church there, they moved again to Washington, D.C., and when Louis was 5 they settled in Albemarle, North Carolina. A few years later, Louis started playing guitar on a “little burgundy sunburst acoustic. Eventually, I busted a string and busted another string and just kept playing with four strings. I delved more into bass from playing bass lines on the acoustic guitar. So, for my 9th birthday, my dad bought me a 4-string bass.”
“I’d show up to Tip’s and we’d do a week of writing sessions with John Legend or have André 3000 in the studio for a couple of weeks.”
While it was strictly pragmatic reasons that initially drew him to the bass, he says his biggest inspiration was the bass player he knew best: his mother’s left hand. Her playing, rooted in the COGIC (Church of God in Christ) style, “involves heavy left-hand bass. I wasn’t as psyched to play bass in church since the way my mom plays is very defined. But eventually I kind of had to learn how she plays. It was always just her and me playing. And I had to learn to move with that and follow that. She’s a great bass player.”
Along the way, Cato picked up more instruments. By the time he headed to Berklee, he was playing drums, guitar, and bass as well as tuba, trombone, and euphonium. “I was going from being a big fish in a small pond to a small fish in a large pond of super-talented people who had heard oodles of music I had never dreamed of,” he recalls. So, he decided to focus his studies on the instrument he’d played the longest.

Cato completed just two semesters—fall ’03 and spring ’04—before deciding to concentrate on playing the gigs that were paying his bills. “My rationale was, much to my parents’ chagrin, here’s an opportunity where I can keep learning on the job and be working my way out of the debt I went into in this year.”
Gigging with wedding and church bands gave the multi-instrumentalist an opportunity to keep all his instrumental and vocal skills alive. “My oldest daughter was born soon after that,” he recalls, “so I felt really, really aware of how lucky I was, how lucky any of us are, to make a living and support a family as a musician.” Cato spent five years in Boston, playing various instruments in gigging bands, and he frequented local institution Wally’s Cafe Jazz Club, just two blocks down the street from Berklee, “for self-education and inspiration. When that felt like I hit a ceiling, I looked at where I could go to continue my inspiration and working on the kind of projects I wanted to be working on, and that led me here.”
By that time, Cato’s friend Meghan Stabile, had moved to New York and created the promotion and production company Revive Music, which was dedicated to the kinds of jazz and hip-hop collaborations he wanted to pursue. Cato moved to Bushwick, Brooklyn, with his band Six Figures— “There were six of us; we did not make six figures!”—and would head back to Boston each weekend for the gigs that were paying his bills. Eager to soak up the New York scene, he’d return to New York on Sunday nights and go directly to jam sessions.
All that time back and forth on the Northeast Corridor paid off. A self-described musical “utility knife,” Cato’s multi-instrumentalism, as well as his talents as a songwriter, arranger, producer, and engineer, made him a major asset as a collaborator, and the New York scene took notice. Soon, he established essential connections that would affect his career, forming “an instantaneous brotherhood that continues to this day” with producer Kamaal Fareed, aka Q-Tip. “Through that, I ended up really delving into a lot of relationships and credits.”
The two artists worked on high-level collaborations that not only bolstered Cato’s reputation but served as a major piece of his education. “I’d show up to Tip’s,” he explains, “and we’d do a week of writing sessions with John Legend or have André 3000 in the studio for a couple of weeks. Sometimes things would come from it, and sometimes nothing would come from it. But being in the creative process on that level in a trusted space was invaluable for me. I learned so much.”
Outside of Q-Tip’s studio, Cato was learning from plenty of masters, mostly from behind the kit. “It’s really special when you find yourself learning things you connect to,” he says about his work alongside artists such as bassist Marcus Miller, keyboardist George Duke, and guitarist John Scofield. “And I learned so much about myself from connecting to some of these people.”
Staying Human
Back in 2015, Cato received a phone call from pianist Jon Batiste. The two had never met, but Batiste rang him up about a mysterious project—a theme song for a TV show that he couldn’t disclose. “I had a wisdom tooth appointment back in Boston, and I got a random call,” Cato remembers. “I think his exact words were, ‘I’d love to have your ears on it.’ And I followed my gut, rescheduled my trip, stayed in New York an extra day with an abscessed wisdom tooth.”
The two got together to co-write and produce “Humanism,” which would become the theme song for the Stephen Colbert-hosted Late Show. Batiste played piano, Cato played the guitar, bass, and drum parts and “put on my editing hat.” They brought in Joe Saylor—who would become the show’s drummer—to play tambourine, as well as saxophonist Eddie Barbash. “After the session,” Cato remembers, “I went back, got my wisdom tooth out, and went back on the road with John Scofield.”
Three of the four go-to guitars Cato uses on The Late Show: a black Tuttle T-style, a cherry-red Gibson SG, and a Martin OM-28.
At first, Cato played the multi-instrumental role of his dreams, attempting to surround himself with every instrument he could play. “That lasted about three days before reality set in,” he laughs. “Slowly, one by one, things started disappearing—a floor tom going away here, a Pro Tools setup going offstage there. Eventually, as the band formed out, I moved around to what was needed. I was the utility guy—played a lot of kazoo, a lot of cowbell.”
While on the road drumming with Sco’, Cato got the invite from Batiste to join the show’s band, Stay Human. “It was a huge life shift for me,” Cato explains. “I was making really good money on the road with really good musicians, which was really fulfilling. And I took a chance. I loved the idea of being a part of something creatively from its inception.”
Eventually, Cato settled into a more consistent electric bass role, until Batiste brought in upright player Endea Owens, and he moved to guitar, where he’s mostly stayed. When Batiste left the show last year, Cato took over as bandleader—officially starting this season, back in September—and decided he’d lead from his role as guitarist. “Of all the places I occupied,” he says, “guitar was the easiest and most natural to me to lead the band, in the energy. From behind the drums, it’s a different thing, and we’ve done it when Joe was out. But it just was a really natural progression.”
Same Show, New Job
In just a few months, Cato’s new role as bandleader has had an impact on the show. The renamed Late Show Band’s engine seems to be burning on a new kind of fuel. And it feels as though that energy is coming directly from Cato.
When we talk, the guitarist is deeply engaged, in a kind of hyper-focused way that is not intense but more casually un-distractable. He brings that same focus to the show. While Colbert delivers monologues, Cato is zoomed in on the host, listening to every word, often riffing around on his guitar to contribute musical commentary. During interviews, he’s taking cues and following the tone of the conversation, looking for ways to adapt.
The bandleader gig requires loads of big-picture improvisation, but also lots of prep. Cato explains that each week he makes a set list, but the band will react and make changes in the moment. “My job ends up being a lot of judgement calls that affect the flow of the show,” he says. “We have a group of compositions we wrote for the show that can complement different moments. If there’s a major energy shift in an interview that takes a turn or something happens in the day, like a tragedy, we’ll call one of the songs we wrote for the show for a moment such as that. Recently, we had a guest on that started improvising a song. So, I have on our in-ear mic and call out the key and start playing, and we all jump in, and now we’re doing this instead.”
Cato poses with his black-sparkle chambered T-style, made by Tuttle. “When I’m checking off core priorities in sound,” he says, “if I’m going for rhythmic things, I go to the Tele.”

Watching the Late Show Band in person, I see this play out as Treasury Secretary Janet Yellen explains the steps the U.S. can take to avoid a recession. It’s a heavy and heady conversation, and, frankly, it’s anything but fun. Cato knows he’ll need to pick the audience back up. As he watches from the bandstand, he gives tempo cues to the band, who nod along, so they can effectively shift the energy and get the audience re-focused for the next guest, actor/director Sarah Polley.
As a guitar player, Cato says he sticks to playing things that feel most natural to him so he can concentrate on his bandleading duties. He adds that he considers himself more a rhythm guitarist than a lead guitarist. (It’s worth noting that his delineation is more conceptual than musical: Cato is an inspired and dynamic melodic lead player, but his deeply rooted phrasing and feel is at the forefront of everything he plays, so the rhythm-first thing applies to it all.) “This is not a space as a guitar player where I’m jumping out of the box trying any and everything and exploring,” he explains. “You get to some of those places. But for me, it always has to start from something I can do while leading the band and reading the energy and making judgement calls.”
“We’re arranging it and making it our own—because that’s the sonic fingerprint of our show.”
That rooted, pragmatic ethos applies to the gear he chooses as well. “I never was a big gear person,” he admits. Luckily, he has Late Show Band tech and informed gearhead Matt Mead to help him keep his pedalboard well-stocked. “There’s so many things I’m learning about the job and trying to keep straight in my head that this ends up getting the short end of the stick, and it wouldn’t work if there was not a Matt Mead to make up the rest of that stick and make it sound good.”
“The show throws a lot of curveballs,” Mead points out. “He steers the boat as far as the tones he’s looking for and if there’s a particular sound he’s looking for. Sometimes, I’ll recommend stuff and say, ‘Hey I notice you’re doing this, maybe we should try this.’”
Cato’s collaboratively curated pedalboard is pretty simple at its core: It starts with a Boss FV-500H volume pedal, a Boss TU-3, a Dunlop Cry Baby, and 3 Leaf Audio Octabvre. Cato shows me how he uses the latter for more traditional, Hendrix-style playing, but he points out that the band plays a lot of montunoes, and he tends to use the octave pedal for those. For drive, he uses a J. Rockett Archer and a Truetone Jekyll & Hyde, which are followed by an Xotic RC Booster and an MXR Carbon Copy, all into a Fender ’65 Princeton Reverb reissue, and powered by a Voodoo Labs Pedal Power Plus.
In live performances outside of The Late Show, Cato uses various guitars, but says that the studio’s cold temperature doesn’t do many favors for instruments such as his Gibson Luther Dickinson ES-335 or some of his acoustics, so he’s careful when selecting which guitars come on stage at the Ed Sullivan Theater. The three guitars that most commonly appear on the show are his black Tuttle Custom Hollow T, a cherry red Gibson SG 1961 Reissue, and a Martin OM-28.
Another guitar that sometimes appears on the Late Show is his LP-style Univox, which I ask Cato about in his dressing room. “If I need to be altogether comfortable,” he explains, “I pull out the Univox, because it’s my earliest guitar. I’ve had this since high school.”
Cory Wong "Lunchtime" - The Late Show's Commercial Breakdown
When musical guests visit The Late Show, they get the full-band treatment from Cato and company. Here, Cory Wong sits in for a rhythm guitar showdown of the highest level.
Back when he first got the guitar, Cato remembers, it was in rough shape, desperately in need of wiring and pickup repairs and a new set of tuners. It stayed that way until he was in Boston. When he picked up a wedding band gig playing trombone and guitar, he was lucky enough to have a roommate who could get the Univox performance-ready by replacing the original tuners with locking units, cleaning out the electronics, and swapping the pickups for a pair of Seymour Duncans.
“I didn’t even know there was a such thing as a professional musician.”
But Cato says that even before those repairs, he’s always “loved it because it’s all I had. I remember I was playing a little Vox amp, and this guitar had a feeling out of that amp. This guitar just became home base and felt super natural to my fingers. If I need to just not be thinking at all, this is home.”
Did he ever dream he’d be on television every night, holding this Univox and chumming with a late-night host? “Never! Not once!” he says. “It was just a product of my nurture growing up in a small town. I didn’t even know there was such a thing as a professional musician.” And yet, Cato pursued music as fully and single-mindedly as he could. “I just knew that I liked it and felt connected to it.”
To go or not to go, and the perils of the no-show.
“The NAMM Show is quickly approaching!”
That’s either a battle cry or a warning, depending on your perspective, heard biannually in the music industry. (At least in non-pandemic years.) The most universal analogy I use for NAMM is: “Think of it as Comic-Con for music gear.” For many of us in the instrument business, the trade show seems to be constantly looming. In addition to convention preparations always occupying the back of our minds, I feel it has also created pressure for companies to release products around its schedule, if not almost dictated it.
I have lived on both sides of the curtain. I used to be in the audience, wondering how I could gain access to the show as an exhibitor. I have also been backstage, directly involved with most of the aspects of presenting Coppersound’s pedals. So, I’ve got a perspective of NAMM from both viewpoints. And with the latest NAMM show just behind us, that perspective is the catalyst for this month’s column.
As an outsider looking in, a big attraction to attending the event is seeing what new products are going to be released by some of my favorite companies. That hunt rarely requires clues because exhibitors typically plaster their booths with media and signage that promotes their newest releases. For us manufacturers, that also raises a big question: “Should a company present at NAMM without a new release?” That query naturally does a cannonball into the pool of philosophy. But for the sake of this article, I would prefer to keep the focus more in the pool of psychology—most notably appearances and perception.
As an insider looking out, I have had many conversations in the past with industry colleagues about all aspects of attending NAMM. We often discuss booth layout, travel plans, shipment logistics, costs, and more. There is also a specific day that we all wait for: the day the show map is made public, and each exhibitor can see the upcoming floor plan. We can see who our booth neighbors are going to be and take stock of what other companies will be attending. And therein lies the root of the most speculation, along with possible concerns.
“What should drive new products is the excitement of innovation and not the notion of releasing something just to release something.”
The showroom floor is filled with many types of companies within the industry, big and small—from single-owner outfits with a small table-top booth to medium operations with five to 10 employees to large household names occupying a booth the size of a mall food court.
Everybody, regardless of size, attracts attention in one way or another. However, it is not uncommon to worry about a lack of attendance if we see large companies—who tend to attract lots of music-store order writers—not attending the event. That’s especially troublesome if there is a lack of big presenters within our own line of business.
If a large, established company does not attend the show, people will notice and ask themselves, “Do they know something we don’t?” If a small, younger company does not attend, it’s quite possible those who are used to seeing that company’s booth will ask, “Are they not around anymore?” Especially in our Covid-tinted world.
I also wonder if attending the NAMM show is the perceived benchmark of determining if one has “made it.” I often define success by the act of achieving a premeditated goal. For those that do not know, registration for NAMM is many months before the show dates. If you are a company that has presented at these shows in the past, you will most likely not want to attend again without a new product. After all, new products are the big attraction. This brings us back to the release schedule for new products. NAMM is traditionally held twice a year: during winter in Anaheim and summer in Nashville. These shows are about six months apart. If a company decides to present at both shows, that entails a pretty intense product-release schedule—especially for small outfits. For larger companies, that’s typically not as difficult. But for even a medium-sized company looking to place and/or keep their flag in the ground, it can still be very tough.
I am a big proponent of the belief that deadlines create productivity. So, the NAMM release schedule may actually be a good thing for companies like ours. However, I feel that what should drive new products is the excitement of innovation and not the notion of releasing something just to release something.
So, while I deliberate our future NAMM events, here’s another thing that’s under my skin: Does anyone else find that the word biannually meaning both twice a year and once every two years is confusing?
Want to play different pedal sequences in a flash? These handy boxes provide more tone solutions than you might realize.
There is no right or wrong way to wire a pedalboard. It’s really a matter of personal taste and what our ears find pleasing. Every musician has their own thing, and our pedalboards are certainly an extension of that. For some, reconfiguring the pedalboard is a lifelong process, and adding a new device often means something has got to go, because real estate is crucial!
Whether you are a fan of effects loops or not, they can be useful tools. One of the go-to pedals in my collection isn’t an effect. It’s a standalone effects loop order switcher, which is basically a pair of dedicated effects loops (A and B) in an aluminum pedal enclosure. There are quite a few companies that make a version of this type of device. Some of these units have many other options included and some are very basic, with no knobs at all. I like to have a somewhat simple one hanging around, with an input, an output, and two sets of send/return jacks. Each channel needs a volume knob, a foot switch, and a bypass indicator light.
A loop switcher can be an especially useful tool when putting together a pedalboard, or even just adding a new stompbox to the mix. Signal paths can be auditioned to see how pedals will interact together before committing them to Velcro. I find it is also super fun and handy to use a switcher when doing sound explorations and, ultimately, in my writing and recording processes. There are so many more options sound-wise, depending on how effects are ordered. The rather simple unit I made allows for quick changes, which helps me economize my time. In fact, it’s so useful that I have one living full-time on my pedalboard, in a really accessible spot, so I can plug and unplug on the fly if something isn’t working out sound-wise.
Fancier loop-switching devices can have true bypass switching, buffers, lots of sends and returns, knobs, signal paths routed any which way.... The options are nearly endless. Plenty of pedal builders out there can build custom units for a reasonable price, tailored to anyone’s specific taste. You might even go the rackmounted, pro-audio hardware route if you want to get extra fancy!
There are several different commercial A/B loop switcher units available that are on the simpler end of the spectrum, like the JHS Switchback A/B Effects Loop Switcher ($102 street) and the MXR M196 A/B Box Pedal ($59 street). The EarthQuaker Devices Swiss Things Pedalboard Reconciler ($249 street) is an awesome utility pedal with a few more helpful options. My absolute favorite simple go-to is the Boss LS-2 Line Selector Pedal ($113 street). It’s got a small footprint and does all the basics. Plus, it’s Boss, so it’s built like a tank. Mine has survived 20 years of abuse so far.
Whether you are a fan of effects loops or not, they can be useful tools.
Some pedals sound totally different when inserted into an effects loop instead of being inserted directly in line. It’s really informative to be able to hear those differences. I feel like a whole new world opened up to me when I started using the LS-2. Some of my favorite sounds that I have been able to create came from putting pedals in the loop that normally get chained up in line directly. Give it a try! And for those who DIY, check out Beavis Audio Research’s awesome site. There are several different iterations to build.
Modern stomps offer more sounds than ever before, but a laptop can help you delve into an even deeper world of live sonic manipulation. Here’s what you need to know to get started.
The beauty of a great guitar plugged straight into a great tube amp is undeniable. Still, some might say the full potential of an electric guitar is realized only when processing that signal. Of course, some of the most groundbreaking players of all time—from Jimi Hendrix to The Edge—have illustrated this point, and the current deluge of new pedals and thriving builders seems to bear this out.
If you are into processing, pedals might be plenty for you, especially in this era of stompboxes that do things even top studio gear couldn’t manage a decade ago. Still, there is a portal to another world of sound available for live use—a world explored by guitarists like Adrian Belew, John McLaughlin, Eivind Aarset, Fennesz, Dan Phelps, the late Andy Gill, and others. It’s a portal you may be looking at as you read this. I am talking about a laptop computer.
I was introduced to the concept of guitar and laptop performance through the series of Warper parties— gatherings dedicated to computer-based music—I attended in New York City. At the very first one, I encountered a guitarist with a computer built into his guitar and another playing jazz fusion through his laptop to backing tracks, also on computer. Yet a third player was performing arrangements of TV themes, playing guitar with one hand and keyboards with the other—all through a laptop.
Plug-ins offer sonic shaping and effect routing that is difficult or impossible to achieve with pedals. Even if you could, it would require a pedalboard the size of the entire stage and a router/switching system of NASA-level complexity.
For me, performing solo with a laptop let me privilege the kind of sonic fairy dust I had been offering as a side musician, shifting the lush pads and textures I had delivered to singer/songwriters for years out from the background and into the focus of attention. Plus, as someone who does not sing or play typical solo guitar, playing through a laptop let me take control of my performance opportunities: no pesky bandmate schedules to consider for rehearsal or booking.
Many guitarists already use a laptop to record everything from demos to final releases. These days, all it takes is a guitar, an audio interface, a DAW (Digital Audio Workstation), and a pair of speakers or even good headphones, and you are ready to make your next masterpiece. If you have worked this way, you have likely discovered plug-ins. Instantiated in a DAW, plug-ins offer sonic shaping and effect routing that is difficult or impossible to achieve with pedals. Even if you could, it would require a pedalboard the size of the entire stage and a router/switching system of NASA-level complexity. Multi-effects units might get you part of the way there but as yet cannot offer the range of potential sounds available with a computer.
With a wealth of creative software, a laptop lets you easily take lush reverbs and mangle them with filters or distortion. You can sequence effects to automatically appear and disappear over the course of a song or composition. If that sounds interesting, you might want to consider transporting your laptop, DAW, and plug-ins to the stage, either as your sole processing system or in conjunction with pedals. Here’s what you’ll need to get started.
Hardware
A MIDI controller, like the Novation Launch Control ($159 street) seen here, isn’t necessary to use Ableton Live, but using one increases interactive functionality.
Because live performance has different requirements than recording, ultra-high audio specs are not quite as important, but portability, reliability, build quality, and low latency are crucial. Latency is the time it takes for your signal to go into the audio interface, pass through the software on the laptop, go back into the interface, and travel out to the speakers, as measured in milliseconds. You will want the latency low enough that you don’t hear the sound reaching your ears noticeably after you hear/feel your pick hit the strings. Ideally, you will want the most powerful laptop you can afford in order to have access to the fastest processor possible. Plenty of RAM and a solid-state drive will contribute to the computer’s speed.
There are factors that affect latency. One is buffer size, delineated in samples. Without getting too technical, the lower you can set the buffer in your DAW, the less latency you will hear. How low you can set it, without getting dropouts and other unwanted glitches, is determined by the number of plug-ins you are running and the power of your computer. With virtually any of the current Apple M1 powered laptops you should be good to go. If you can’t afford a new computer, don’t worry. I was performing with a MacBook Pro over a decade ago with no problems. You can attempt this with a non-Apple computer, but virtually every major touring act uses Macs thanks to their reputation for reliability.
Here I have the buffer size set to 128, where I find I can record tracks without latency issues. With modern computer power and minimal plug-ins, you can probably set this even lower.
To plug your guitar into your computer, you will need an interface, which converts your signal from analog to digital. There are many available options, including the Universal Audio Arrow (available used for $350-$399) or Focusrite Scarlett ($179 street). You only need one input, unless you use both electric and acoustic guitars, which have different input requirements. The number of outputs will depend on your signal chain.
A MIDI controller of some sort—foot switcher, tabletop controller, or both—is a good idea because, as with pedals, you will want to turn effects on and off and have access to parameters. Akai, Korg, and others make a variety of tabletop controllers, ranging from $119 street and up, with knobs and switches that will let you turn on, blend, and manipulate the parameters of the plug-ins in your DAW.

You might be thinking, “Aren’t my hands otherwise occupied playing my guitar?” That’s true, but one of the advantages of laptop guitar is advanced looping. Once a loop is created, a tabletop controller lets you easily route that loop through myriad effects—filters, resonators, delays, reverbs—in ways that are impossible with hardware loopers. A footswitch-style MIDI controller is helpful if you want to do sync’d rhythmic loops, though it’s not as necessary for ambient looping.
Software
To process your guitar in the computer, you can use any software that hosts plug-ins: Logic, Pro Tools, GarageBand, Logic MainStage, and others. As a performing tool, Ableton Live (starting at $99 street for an introductory version) is the most ideal and offers a number of unique features. With Ableton, you can tap in tempo, easily syncing all your effects and loops at once, and there are “nudge” buttons that let you move the tempo of loops slightly up or down to match a drummer’s shifting time without changing their pitch. The “link” feature lets you wirelessly sync your effects with your keyboard player’s laptop, your drummer’s loops, and even the computer running the show’s backing tracks and light show.
This is my performance setup in Ableton Live. It includes the Jam Origin MIDI Guitar plug-in ($149 street) that lets me control spoken-word recordings in a sampler without any kind of MIDI pickup on my guitar. Also shown is a great granular processing plugin, Stream, from Delta Sound Labs ($49 street).
Live’s native plug-ins will let you create a custom amp-modeling system; emulate digital, analog, and tape delays; and add stutter, granular, or bit-crushing effects. Plus, if you are performing solo using backing tracks and running through a PA, you can easily set a dedicated track to resampling and it will record your entire evening’s performance.
Live lets you loop in two different ways via the looper plug-in and “clip” system. The looper plug-in is great for overdubbing ambient soundscapes, but can also provide timed rhythmic parts, while the clip system is perfect for making multiple rhythmic-based loops that can then be triggered by a MIDI footswitch and/or tabletop controller. While you can’t overdub on a clip, you can set up multiple clip loop tracks where you are able to, for example, record all your verse parts in one row, your chorus parts in a second row just below, and create a third row for the bridge. You can then trigger these rows as scenes.
Here is a dummy clip set to raise and lower the feedback of the Ableton echo plug-in.
Live also lets you make “dummy” clips with no audio that can be set to modify effects parameters over time. For example, you could set a dummy clip to increase a delay plug-in’s feedback to just under runaway levels while simultaneously shortening the delay over a period of two bars, and then reverse the process over the next two bars. Try that with pedals!
Would you like to hear two great examples of guitarists using Ableton Live onstage? Check out any video with Eivind Aarset performing. Aarset uses it for a variety of sounds, including ambient reverbs and delays and looping. John Scofield collaborator Avi Bortnick also uses Live for myriad sounds and textures, one of which includes using his guitar to open a noise gate that lets rap vocals cut through only when he plays.
Signal Path
Fig. 1 (*Magenta cables indicate additional or alternative signal path.)
There are multiple ways to insert a laptop into your signal chain. You can run everything through your computer, employing amp modeling software—like Bias FX 2 ($49 street), Guitar Rig ($199 street), or AmpliTube ($99 street)—and running the signal from your audio interface to the house PA or a pair of powered monitors (Fig. 1).
Fig. 2
You might instead eschew the amp modeling software and run the signal into a pair of guitar amplifiers (Fig. 2). This offers a way to keep your favorite tube amps as part of your rig. But be careful: Some effects plug-ins can put out low frequencies that don’t work well with guitar amps and speakers.
For both of those methods, all you need is an interface with one input and two outputs. You run your guitar signal into the interface, which converts your analog signal to digital, and then sends that digital info through USB, Lightning, or Thunderbolt cables into the laptop and the software. Next, a stereo digital signal is sent back to the interface, where it is converted to stereo analog and sent out to the amps, powered speakers, or PA using standard guitar cables or XLR-style microphone cables.

A more complicated method is a version of the wet-dry-wet setup. Here you would split your guitar signal between a mono signal going directly into a guitar amplifier and the laptop’s stereo output to two full-range powered speakers or the PA. This setup can be achieved in a few ways. You can use an interface with one input and three or more outputs that can be routed inside the interface. This allows you to send your guitar signal from the interface simultaneously to the laptop and directly to a guitar amplifier (Fig. 3).
Fig. 4
Alternately, you could use a splitter box before the audio interface that sends one signal to your interface and computer, and one to the amp (Fig. 4).
Fig. 5
If you don’t want to use modeling software in the computer for the wet signal, you can use a reactive load box, like the Universal Audio OX ($1,499 street) or Fryette’s Power Station ($899 street) or Power Load ($699 street), which gets placed between your amplifier and its speaker (Fig. 5). You run your guitar into the amp, and two outputs on the load box simultaneously send your amp signal to the speaker and, with speaker emulation, to the computer interface. Sending the sound of your amplifier to the DAW means there is no need for amp modeling within the computer. Once the sound is processed, it is sent to powered speakers or the PA, as in Fig. 2. In this method, your amplifier signal can remain dry and present, while processed sounds will emanate from the powered speakers or PA.
If you don’t want your amplifier signal completely dry or just want to place some of your effects pre-computer, you may want to use pedals in front of your amp. Which brings us to.…
Pedals and Laptop
As much as a computer can do, there are plenty of good reasons to combine pedals with laptop sounds. Digital modeling software sounds excellent these days, but adding a mild overdrive pedal before your interface can lend some analog warmth to the sound. In addition, a drive pedal set for just a little breakup can make the playing experience feel more organic. As you play harder and softer, the “give” of the pedal can often feel more expressive than even the best amp modeling software.
Plus, just as many plug-ins are not yet duplicated in pedal form, likewise there are pedals that perform functions not available as plug-ins. Glitchy, digital micro-looping pedals like the Red Panda Tensor, Hologram Electronics Dream Sequence, Chase Bliss’ Blooper and Mood, and the Hexe FX Revolver do not yet have any direct analogs in the plug-in world. If you want to learn a programming language like Max MSP, you might be able create something like these pedals inside your computer. Ableton includes Max for Live with the purchase of their suite and a plethora of pre-programmed plug-ins are available using Max as their basis, but these pedals still offer something special.
Taking the Stage
You now have all your hardware and software and are ready to perform. Depending on how you use the laptop in your signal chain, you might be able to place it out of the way and use a foot switcher, as if you were using a standard multi-effects unit. But if you want to maximize the advantages of using a computer live, you will likely want it at hand.
In almost two decades of performing with this setup, I have had fewer computer crashes than pedal malfunctions.
You can normally rely on the venue to provide a table of some sort, or you could try Eivind Aarset’s solution. He brings a keyboard stand and places his guitar’s hard case on it, creating a perfect platform for controller, computer, interface, and some of his hardware pedals. I haven’t used a hard case in years, so I just screwed some handles onto a painted piece of plywood and place that on a keyboard stand.
As with any performance, hearing yourself is crucial. If you are using guitar amps or powered speakers, they will act as monitors. Some powered speakers may have XLR outs to send to the house PA. If you are only running through the PA, you may want to use headphones plugged into your interface to be assured of hearing the same thing as the audience.
Some guitarists have trepidation about reliability when using a laptop. All I can say is that in almost two decades of performing with this setup I have had fewer computer crashes than pedal malfunctions. It is also easier to bring a backup laptop and interface than a second pedalboard and amp.
A laptop dedicated to only music is ideal, but if you don’t have that luxury, make sure to quit any programs other than the performing software in use. Turning off WiFi during your set will prevent notifications from interrupting and provide a little extra processing power. And speaking of power, while it is best to keep your laptop plugged in while performing, if there is ever an issue with clean power or a faulty socket, unlike with pedals, your laptop battery will take over and the show will go on.
Is It for You?
Playing through a laptop is not for everyone. You probably won’t be welcome at your local blues jam if you say, “Hang on a minute while I boot up my Mac.” But if your music involves a world of sounds that go well beyond those offered by hardware pedals and multi-effects, or you’re just seeking a more portable way of producing interesting tones, taking the stage with a computer might be an option. And, with tubes becoming harder to get, who knows? Someday it may be the best option.
