Line 6 Catalyst 100
line6.com
Line 6’s Catalyst series is the latest in a generation of amplifiers bridging the gap between digital modeling’s enormous possibilities and many players’ desires for old-school simplicity. These amps offer detailed, convincing amp models—but not too many of them—in a compact, vintage-style design that makes avoidance of option fatigue a priority. The very accessible prices also make the series a direct competitor to Boss’ ultra-successful Katana amps. The Catalyst is offered in three models: Catalyst 60 and Catalyst 100 (both of which have one 12" speaker), and the Catalyst 200, which has two 12" speakers. For this review I tested the Catalyst 100, which sells for a very modest $399.
Simple Complexity
The Catalyst has plenty of bells and whistles. On the surface, though, it looks a lot like a simple, conventional 2-channel amp. There are knobs for boost, gain, bass, mid, treble, presence, channel volume, effect, reverb, and master volume. There’s also a knob that lets you choose from six original amp models: clean, boutique, chime, crunch, dynamic, and hi gain. Mini buttons let you save and choose between two channel presets or engage manual mode, where what you see is what you get. Other mini buttons allow you to engage boost, tap tempo, and select effects and a tuner. On the back panel is an output power knob that lets you choose from mute, ½ watt, 50 watts, and 100 watts. There’s also a USB jack, a DI out, and an effects loop.
Six Amps in One
There’s not enough space in this review to cover all the amp models in depth. And I suspect that for many players even just a few used through the full range of their clean and dirty variations will be everything they ever need. Still, the Catalyst’s abilities and potential—especially relative to its price—will excite any potential user.
I started my own experiments with the boutique voicing at the ½-watt output setting. Predictably, there’s not a lot of output in this mode, though it’s a lot of fun as a practice amp. At the 50-watt output setting, though, I could hear and feel the amp in a more complete way. There was headroom to spare and it’s impressively dynamic and responsive to picking nuance. And it was surprisingly easy to get SRV-style bite out of otherwise clean, blues-tinged phrases—again, very impressive. The useful boost knob lets you dial in extra kick, and, thoughtfully, each amp model has a specifically tailored boost voicing. In boutique mode higher boost settings added a lot more gain to the amp model’s cleanish sound, and the saturation sounded and felt organic.
The chime model, loosely inspired by a Vox amp, is warmer and thicker than the boutique model in cleaner settings. But when I engaged the boost (with the knob at noon) and set the gain knob around 11 o’clock, the amp positively screamed—generating an aggressive and at times piercing sound that would reward a player with a commanding approach like Eric Gales or a 1960s-influenced guitarist who loves the potency of single-note lines.
The high-gain model, meanwhile, is a fire-breathing beast. With the gain at 11 o’clock, there is plenty of bottom end, and the sensation of the amp moving air becomes more apparent. Engaging the boost softened the attack slightly, which made soloing more liquid. But there wasn’t much of a difference through the range of the boost knob from noon to max. The amp model is pretty saturated to begin with.
There was headroom to spare and it’s impressively dynamic and responsive to picking nuances.
No Jumping Through Hoops Running Loops
Using the clean model, I ran my Yamaha UD Stomp delay through the effects loop. The results were dimensional and often sublime. The power-amp-in feature lets you plug in a pedalboard and play it directly into the Catalyst 100’s power amp. I used another setup, with a Mesa/Boogie V-Twin preamp pedal, directly through the Catalyst’s power amp and it sounded phenomenal. And even though the preamp is bypassed in this mode, the boost function is still active. Set at 10 o’clock, it added a nice final touch to the Mesa/Boogie preamp’s clean channel, making it sound discernibly richer. In my humble opinion, just the power amp and speaker cabinet alone are worth the $399 price.
Though Line 6’s acclaimed HX technology is embedded in the Catalyst, the company did a good job of keeping options easy to manage and navigate. There isn’t an endless buffet of effects, as you might expect. There’s a standalone reverb, and apart from that you can only use one additional effect simultaneously, unless you bring your pedalboard to the party.
In total there are 18 effects, grouped into three categories: delay, modulation, and pitch/filter—each with a corresponding LED in green, blue, or purple, respectively. If you’ve used Line 6 products before, many of these excellent effects (and the color coding) will be familiar. There’s the fabulous dynamic “ducking” delay, some modulation models based on iconic pedals like the MXR Phase 90 and others, and some classic Line 6 pitch/filter effects like growler synth and synth strings. If you do want to use more effects simultaneously, the effects loop is an excellent way to patch in external effects.
The USB hookup, by the way, enables connection to a computer so you can use Line 6’s editing software, which allows you to dive deep into tone editing or just fine tune a few things. I imagine that, in reality, most users will just figure out how to get a couple of core sounds directly from the amp, save them, and just go with that. But it’s always great to have options, and if you’re someone that actually maximizes the capabilities of modelers and editors, you’ll have a field day with the app.
The Verdict
For any guitarist looking for an all-in-one, plug-and-play setup for practice sessions, live shows, and recording (you can record directly using both USB and the built-in DI with cab simulation), the Catalyst, at $399, is pretty tough to beat. It’s got more features than many players will need, but what will count for most of the target audience is how much you can accomplish without diving too deep. And though the price might suggest otherwise, Catalyst isn’t just for beginners or intermediate players. Any professional guitarist that’s tired of dealing with tube related maintenance and expenses will be happy with many of the sounds here.

• Get familiar with power chords on every string set
• Create new sounds with tried-and-true shapes
• Use the entire neck with compelling power-chord-based lines
We all know that grip, but power chords actually come in many forms and sizes, and they fit equally well in a powerful riff or a more ethereal-sounding part. This lesson presents a handful of examples aimed at extending your power-chord vocabulary, with particular attention to range and orchestration.
Power chords represent a true staple for many of us guitarists. Accessible yet captivating, they provide the foundation for a lot of music we love. I still remember the countless hours spent playing Nirvana or Green Day riffs when I first picked up the guitar. Fast-forwarding to my current career as a session player, I’ve found myself extending the use of power chords to many different purposes and styles.
Power chords indeed come in many shapes, making for a comprehensive tool to have in your arsenal. In this lesson I’m going to focus on a few key aspects:
- No matter where and how you play them, power chords always sound tight, economical, and effective, tracking really well even when using large amounts of distortion, reverb, or delay.
- Power chords are well known for delivering dynamic, high-energy parts in the low/mid register, but they work equally well for creating textures in the higher portion of the fretboard.
- Power chords are versatile, and they feel “at home” in a wide variety of genres and styles.
The first part of the lesson focuses on extending our knowledge of power chord shapes across the fretboard, and is made up of four preparatory exercises, each one focusing on a specific key, set of strings, or guitar arrangement. The second part of the lesson is aimed at providing six practical applications of these concepts, spanning different styles of music.
The main goal of this exercise is to develop familiarity with power chord shapes that start from the 5th of a given chord (5-1-5), instead of just the root (1-5-1). When combining the two, it is possible to play multiple iterations of the same chord progression up and down the neck on a string-set of your choice, providing more flexibility in terms of range and voicing. Ex. 1 illustrates a I-V-VI-IV chord progression in the key of E, to be executed using three-note power chords on the 6th, 5th, and 4th strings. The style chosen for this sequence is fairly common to a lot of rock and pop-rock applications.
Ex. 2 is structured exactly as Ex. 1, but changing the key, string set, and guitar arrangement. Here you’ll find a I-V-VI-IV chord progression in the key of A, played using three-note power chords on the 5th, 4th, and 3rd strings. The style chosen for this example is a palm-muted arpeggio with a nostalgic, ’80s feel and sound. Notice how, despite the key, the shapes of each chord are the same as the ones in Ex. 1.
Ex. 3 is another iteration of the same concept. This example illustrates a I-V-VI-IV chord progression in the key of D, to be played using three-note power chords on the 4th, 3rd, and 2nd strings. The sequence is executed using a syncopated funk pattern. You’ll notice how the two basic power-chord shapes (1-5-1 and 5-1-5) present a different fingering on this specific string set compared to the previous two exercises, but the interval structure of the chords does not change.
As the last preparatory exercise, Ex. 4 is a I-V-VI-IV progression in the key of G, to be played using three-note power chords on the 3rd, 2nd, and 1st strings. The style for this one is a classic palm-muted arpeggio using a dotted-eighth-note delay. These shapes might feel a little unconventional, but they make for a great resource when playing textures in the upper register of the guitar.
Ex. 5 is what I call “fake drop tuning.” I find this application to be extremely helpful to add depth to riffs in the lower register, especially for heavier styles of music. The idea is to substitute in standard tuning any power chord in root position (1-5-1) with its inversion starting from the 5th degree (5-1-5), allowing us to “simulate” the sound of a drop tuning (drop D on this example).
Ex. 6 implements power-chord shapes on different sets of strings, allowing us to play a high-register/textural part conveniently contained in a box between the 12th and 17th frets. Some passages of this exercise include notes that aren’t just roots and fifths, albeit still in line with the diatonic nature of the harmonic sequence.
Ex. 7 features a different way of articulating a two-note power chord (1-5), by playing the fifth not on the string right next to where the root is, but skipping to the next highest one instead. The end result is a leaner-sounding alternative to a standard shape, and can be quite helpful when playing chord melodies in the mid-to-high register of the guitar.
Using a similar approach to Ex. 6, Ex. 8 implements power-chord shapes on different sets of strings to craft a fast-paced funk guitar part in the style of Cory Wong. Notice how the entire chord progression is contained in a total of six frets.
Ex. 9 shows a way to use two-note power chords to imply a certain harmonic sequence over a pedal point. On this specific instance, the pedal is provided by an open D string, with power-chord shapes on the 2nd and 3rd strings layered on top, configured both as 1-5 and 5-1.
Ex. 10 is one last arrangement featuring a combination of power-chord shapes in a box. The goal stays the same: to create a guitar part that sits in a specific part of the mix, providing a distinctive sonic quality. All chords are embellished with notes that aren’t just roots and 5ths, but still in line with the diatonic nature of the progression.
I hope these examples were able to provide some fresh new ideas on how to use power chords in a variety of settings. I encourage you to make these concepts your own, and to try to apply them when crafting a new guitar part. You might find the simplicity of power chords refreshing and, ultimately, inspiring.

Danelectro Spring King Junior
danelectro.com
Few pedal effects were transformed, enhanced, and reimagined by fast digital processors quite like reverb. This humble effect—readily available in your local parking garage or empty basketball gymnasium for free—evolved from organic sound phenomena to a very unnatural one. But while digital processing yields excellent reverb sounds of every type and style, I’d argue that the humble spring reverb still rules in its mechanical form.
Danelectro’s Spring King Junior, an evolution of the company’s Spring King from the ’aughts, is as mechanical as they come. It doesn’t feature a dwell control or the huge, haunted personality of a Fender Reverb unit. But the Spring King Junior has a vintage accent and personality and doesn’t cost as much as a whole amplifier like a Fender Reverb or reverb-equipped combo does. But it’s easy to imagine making awesome records and setting deep stage moods with this unit, especially if 1950s and 1960s atmospheres are the aim.
Looking Past Little
Size factors significantly into the way a spring reverb sounds. And while certain small spring tanks sound cool—the Roland RE-201 Space Echo’s small spring reverb for one—it’s plain hard to reproduce the clank and splash from a 17" Fender tank with springs a fraction of that length. Using three springs less than 3 1/2" long, the Accutronics/Belton BMN3AB3E module that powers the Spring King Junior is probably not what you want in a knife fight with Dick Dale. Even so, it imparts real character that splits the difference between lo-fi and garage-y and long-tank expansiveness.
In very practical and objective terms, the Danelectro can’t approach a Fender Reverb’s size and cavernousness. Matching the intensity of the Spring King Junior’s maximum reverb and tone settings to my own Fender Reverb’s means keeping dwell, mix, and tone controls between 25 to 30 percent of their max. Depending on your tastes, that might be a useful limitation. If you’ve used a Fender Reverb unit before, you know they can sound fantastically extreme. It’s overkill for a lot of folks, and the Spring King Junior inhabits spaces that don’t overpower a guitar or amplifier’s essence. Many players will find the Spring King Junior simply easier to manage and control.
There are ways to add size to the Spring King Junior’s output. An upstream, edgy clean boost will do much to puff up the Danelectro’s profile next to a Fender. The approach comes with risk: Too much drive excites certain frequencies to the point of feedback. But the Junior’s mellower sounds are abundant and interesting. Darker reverb tones sound awesome, and combined with modest reverb mixes they add a spooky aura to melancholy soul and spartan semi-hollow jazz phrasings—all in shades mostly distinct from Fender units.
Watch Your Step!
Spring reverbs come with operational challenges that you won’t experience in a digital emulation. And though the Spring King Junior is well built, its relative slightness compounds some of those challenges. The spring module, for instance, is affixed to the Spring King Junior’s back panel with two pieces of foam tape. And while kicking a spring reverb to punctuate a dub mix or surf epic is a gas, the Spring King Junior can be susceptible to less intentional applications of this effect. At extra-loud volumes, the unit picks up vibrations from the amplifier’s output when amp and effect are in tight proximity. And sometimes, merely clicking the bypass switch elicits an echo-y “clank”. This doesn’t happen in every performance setting. But it’s worth considering settings where you’ll use the Spring King Junior and how loud and vibration-resistant those spaces will be.
Though the Spring King Junior’s size makes it susceptible to vibration, many related ghost tones—taken in the right measure—are a cool and essential part of its voice. It’s an idiosyncratic effect, so evaluating its compatibility with specific instruments, amps, studio environments, and performance settings is a good idea. But for those that do find a place for the Spring King Junior, its combination of tone color, compact size, and hazy 1960s ambience could be a deep well of inspiration.

After eight years, New Orleans artist Benjamin Booker returns with a new album and a redefined relationship to the guitar.
It’s been eight years since the New Orleans-based artist released his last album. He’s back with a record that redefines his relationship to the guitar.
It is January 24, and Benjamin Booker’s third full-length album, LOWER, has just been released to the world. It’s been nearly eight years since his last record, 2017’s Witness, but Booker is unmoved by the new milestone. “I don’t really feel anything, I guess,” he says. “Maybe I’m in shock.”
That evening, Booker played a release celebration show at Euclid Records in New Orleans, which has become the musician’s adopted hometown. He spent a few years in Los Angeles, and then in Australia, where his partner gave birth to their child, but when he moved back to the U.S. in December 2023, it was the only place he could imagine coming back to. “I just like that the city has kind of a magic quality to it,” he says. “It just feels kind of like you’re walking around a movie set all the time.”
Witness was a ruminative, lonesome record, an interpretation of the writer James Baldwin’s concept of bearing witness to atrocity and injustice in the United States. Mavis Staples sang on the title track, which addressed the centuries-old crisis of police killings and brutality carried out against black Americans. It was a significant change from the twitchy, bluesy garage-rock of Booker’s self-titled 2014 debut, the sort of tunes that put him on the map as a scrappy guitar-slinging hero. But Booker never planned on heroism; he had no interest in becoming some neatly packaged industry archetype. After Witness, and years of touring, including supporting the likes of Jack White and Neil Young, Booker withdrew.
He was searching for a sound. “I was just trying to find the things that I liked,” he explains. L.A. was a good place for his hunt. He went cratedigging at Stellaremnant for electronic records, and at Artform Studio in Highland Park for obscure jazz releases. It took a long time to put together the music he was chasing. “For a while, I left guitar, and was just trying to figure out what I was going to do,” says Booker. “I just wasn’t interested in it anymore. I hadn’t heard really that much guitar stuff that had really spoke to me.”
“For a while, I left guitar, and was just trying to figure out what I was going to do. I just wasn’t interested in it anymore.”
LOWER is Booker’s most sensitive and challenging record yet.
Among the few exceptions were Tortoise’s Jeff Parker and Dave Harrington from Darkside, players who moved Booker to focus more on creating ambient and abstract textures instead of riffs. Other sources of inspiration came from Nicolas Jaar, Loveliescrushing, Kevin Shields, Sophie, and JPEGMAFIA. When it came to make LOWER (which released on Booker’s own Fire Next Time Records, another nod to Baldwin), he took the influences that he picked up and put them onto guitar—more atmosphere, less “noodly stuff”: “This album, I was working a lot more with images, trying to get images that could get to the emotion that I was trying to get to.”
The result is a scraping, aching, exploratory album that demonstrates that Booker’s creative analysis of the world is sharper and more potent than ever. Opener “Black Opps” is a throbbing, metallic, garage-electronic thrill, running back decades of state surveillance, murder, and sabotage against Black community organizing. “LWA in the Trailer Park” is brighter by a slim margin, but just as simultaneously discordant and groovy. The looped fingerpicking of “Pompeii Statues” sets a grounding for Booker to narrate scenes of the homelessness crisis in Los Angeles. Even the acoustic strums of “Heavy on the Mind” are warped and stretched into something deeply affecting; ditto the sunny, garbage-smeared ’60s pop of “Show and Tell.” But LOWER is also breathtakingly beautiful and moving. “Slow Dance in a Gay Bar” and “Hope for the Night Time” intermingle moments of joy and lightness amid desperation and loneliness.
Booker worked with L.A.-based hip-hop and electronic producer Kenny Segal, trading stems endlessly over email to build the record. While he was surrounded by vintage guitars and amps to create Witness, Booker didn’t use a single amplifier in the process of making LOWER: He recorded all his guitars direct through an interface to his DAW. “It’s just me plugging my old Epiphone Olympic into the computer and then using software plugins to manipulate the sounds,” says Booker. For him, working digitally and “in the box” is the new frontier of guitar music, no different than how Hendrix and Clapton used never-heard-before fuzz pedals to blow people’s minds. “When I look at guitar players who are my favorites, a lot of [their playing] is related to the technology at the time,” he adds.

“I guess I have a problem with anything being too sugary. I wanted a little bit of ugliness.”
Inspired by a black metal documentary in which an artist asks for the cheapest mic possible, Booker used only basic plugins by Soundtoys, like the Decapitator, Little AlterBoy, and Little Plate, but the Devil-Loc Deluxe was the key for he and Segal to unlock the distorted, “three-dimensional world” they were seeking. “Because I was listening to more electronic music where there’s more of a focus on mixing than I would say in rock music, I think that I felt more inspired to go in and be surgical about it,” says Booker.
Part of that precision meant capturing the chaos of our world in all its terror and splendor. When he was younger, Booker spent a lot of time going to the Library of Congress and listening to archival interviews. On LOWER, he carries out his own archival sound research. “I like the idea of being able to put things like that in the music, for people to just hear it,” says Booker. “Even if they don’t know what it is, they’re catching a glimpse of life that happened at that time.”
On “Slow Dance in a Gay Bar,” there are birds chirping that he captured while living in Australia. Closer “Hope for the Night Time” features sounds from Los Angeles’ Grand Central Market. “Same Kind of Lonely” features audio of Booker’s baby laughing just after a clip from a school shooting. “I guess I have a problem with anything being too sugary,” says Booker. “I wanted a little bit of ugliness. We all have our regular lives that are just kind of interrupted constantly by insane acts of violence.”
That dichotomy is often difficult to compute, but Booker has made peace with it. “You hear people talking about, ‘I don’t want to have kids because the world is falling apart,’” he says. “But I mean, I feel like it’s always falling apart and building itself back up. Nothing lasts forever, even bad times.”

To go along with the record, Booker produced a string of music videos influenced by the work of director Paul Schrader and his fascination with “a troubled character on the edge, reaching for transcendence.” That vision is present in the video for lead single “LWA in the Trailer Park.”
