Picture this. You've just come home from a long day at work. It's time to kick back, plug in, and let off some steam while playing your guitar.
How do you typically play for fun while at home? Lug out your half stack? Grab that tin-y sounding practice amp from the closet that you purchased 20 years ago?
With Spark Pearl, there's a way to practice, jam and record in style – right there in your living room – and sound great while doing it with access to an endless well of inspiring tones. Positive Grid's brilliantly limited version of one of the industry's most popular desktop amplifiers, Spark Pearl offers all of the same crowd-pleasing smart features of the original amp, like Smart Jam, Auto Chords, and access to over 10,000 tones.
Plus, with its snowy white tolex, gold piping and contrast-stitched custom strap, you'll proudly display it in your living room or home studio. (I mean, just look at that thing!) Spark Pearl is a Bluetooth speaker too, perfect for streaming your favorite tunes to liven up any social gathering.
On its own, Spark Pearl offers seven high-quality amp settings to choose from, including hi-gain, clean and crunch. These sounds can be customized further with bass, mid and treble tone stack controls, plus mod, delay and reverb effects. Users can also save up to four tones directly to the amp for later use.
However, Spark Pearl's inspiring tone creation capabilities go way beyond the amp itself. With the companion Spark app, players can access the same tone engine that put the original Spark on the map. Here, guitarists can craft tones virtually using 30 tube amps and 40 effects powered by Positive Grid's BIAS technology, for perfecting that signature tone of their favorite player or discovering a unique sound of their own. They can also share their sounds using Positive Grid's online ToneCloud, which is home to over 10,000 tones created by famous guitarists, session players, engineers and producers from around the world.
Most pieces of guitar gear are designed with one person in mind -- the guitarist. As a result, thousands of amps and pedals have suffered the fate of being banished to basements, home offices and other designated practice areas. With a compact design highlighted by custom white tolex and gold piping, Spark Pearl looks like it could be a piece of modern home décor just as much as a guitar amp. So whether you want to jam in your living room, bedroom, kitchen, or anywhere else in your house, take comfort knowing that you'll look good in the process - so much so that you'll finally not get yelled at for leaving your gear sitting out in the living room!

When it comes to effects like phase, chorus, and vibrato, many of us tend to have a staple (and sometimes cheesy) sound in mind. But such preconceptions obscure the reality that these effects can be much more radical than their best-known applications.
If you’ve ever thought that phaser pedals are one-trick ponies, All-Pedal’s new Microdose, a digital phaser collaboration with Portland’s Spaceman Effects, will happily relieve you of that notion. The Microdose is to the MXR Phase 90 what the modern smartphone is to an old Nokia flip phone: It’s so feature-packed and overflowing with an embarrassment of tone riches that it feels barely related at all to its humble ’70s ancestor.
“It gets percussive, punchy, and juicy, turning single-note runs into intergalactic transmissions, and full chords into blasts of alien goop.”
Discoveries From the Outer Reaches of Space(man)
The Microdose is an evolution and expansion of Spaceman’s Explorer Optical Phaser. It’s maximalist in terms of both enclosure art and functionality, and can feel a bit cluttered as a result. Between eight knobs, two switches, two footswitches, and a groovy font and graphics vying for visibility there is a lot to take in. There are a lot of sounds too. The crowning achievement here is the collection of 16 wave forms—more than triple the Explorer’s five—all of which are selectable via an 8-stop rotary knob and a switch that moves between standard or alternative (and weirder) versions of each wave form. Each setting can be treated to two-, four-, or eight-stage phasing, and the level control provides a hearty boost for the effect to make sure that when its engaged, differences between settings won’t get lost.
Rate, multiplier, blend, and depth knobs all function as you’d expect them to, but the Microdose’s resonance and warp controls breathe new life into familiar sounds. Resonance controls phaser feedback, generating gentle, tried-and-true phase sweeps at low settings and more prominent, insistent phasing when cranked the other way. Coupled with the depth knob, it allows for precise tuning of intense phase sounds. The warp knob, meanwhile, does exactly what it says: At noon, the phase wave form remains unaltered, but turning it in either direction produces varied modifications to each wave form.
The Microdose’s tap tempo is a welcome addition that adds flexibility and more control over complex modulations—especially in live situations. But with such a vast expanse of sounds on tap and no preset functionality, the pedal’s usefulness on stage can feel limited. While dedicated phase jockeys will no doubt find a spot for it on their gigging boards, it sometimes feels more like a piece of studio kit.
Mind-Expanding Tones
The Microdose lives up to its name. It can give you a subtle, just-fun-enough, vintage experience if that’s what you’re after. But it can also blast way beyond that into sci-fi, psychedelic, and fearsome ghost-in-the-machine meltdowns that sound nothing like guitar.
Set for a classic, two-stage sine wave phase with all controls at noon, the Microdose is surprisingly unassuming, adding just a sliver of movement and dimension. This is where the pedal’s dense tweakability really shines. You can dial in a modest always-on sound that breathes life and unusual texture into rhythm or lead parts without overpowering your signal. Deep depth and blend will swing you well into Waylon Jennings territory, but that’s just the start.
Things get trippy in the best way possible as you add phase stages and explore the alternative wave form algorithms, which are a lot of fun on their own and even more so with a wiggle of the warp knob. With each bump up in stages, the effect gets waterier and three-dimensional, which feels like splashing around in some interstellar swamp. When you max out at eight, the effect is in the driver’s seat. It gets percussive, punchy, and juicy—turning single-note runs into intergalactic transmissions, and full chords into blasts of alien goop.
The Verdict
There’s a whole world of sounds here between the Microdose’s extremes. It can probably execute every single phase sound you’ve ever dreamed of—plus some wackier than what your puny human brain could come up with without lysergic inspiration. If you’re up for a phase experience, Microdose is a trip you’ll want to take. PG
Changing their spots, the Black Keys—Pat Carney and Dan Auerbach (foreground)—embraced collaboration full-on for their new album, with the tongue-in-cheek title Ohio Players.
There are so many facets and reflections, so many angles beaming influences and ideas … and it’s clearly the product of time—a work Dan Auerbach and Patrick Carney say they could not have completed earlier in their partnership, although there has been lots of groundwork along the way.
“It’s amazing to be 20 years into our career and have a new trick to be able to do, which is collaboration,” says Auerbach, when asked about the sprawl of styles and the roster of mighty contributors—including Noel Gallagher and Beck—on Ohio Players. “That’s kind of the key to most people’s success throughout musical history, but we’ve shied away from it, extremely. Now, it’s lit a fire under our asses, and the possibilities feel endless.
“Pat and I are at the point in our careers where we feel like letting other people into our space. We never used to be.”—Dan Auerbach
“We were just too insecure back in there,” he continues. “But now we’ve produced enough records, we’ve worked with enough people, so it’s really fun for us. Pat and I are at the point in our careers where we feel like letting other people into our space. We never used to be. And at the same time, our own relationship is tighter than it’s ever been.”
The Black Keys - Beautiful People (Stay High) ("Official" Video)
Revisiting the Black Keys’ first two albums, The Big Come Up and Thickfreakness, it’s hard to imagine they would become an international juggernaut and that Auerbach, their singer and guitarist, would evolve into one of the most interesting players, producers, and songwriters in modern American music. After all, the duo’s initial recordings were raw as uncooked bacon—recorded in a basement in Akron, Ohio, with mics bought on eBay—and their repertoire bridged garage rock and a style, cultivated by North Mississippi hill country rural bluesmen Junior Kimbrough and R.L. Burnside, that’s so rough and thunderous that even some hardcore fans of that genre had difficulty comprehending it.
But Auerbach and Carney’s intelligence, empathy, and history as collaborators might be more apparent to their fans than it seemingly was, at least until this album got underway a few years ago, to them. Starting with 2008’s Attack & Release, they’ve worked with Danger Mouse as a producer and co-writer; Mos Def, Ludacris, Q-Tip, Ol’ Dirty Bastard, RZA, and other hip-hop luminaries on their 2009 Blakroc album; North Mississippi firebrands Kenny Brown and Eric Deaton on 2021’s blues payback Delta Kream; even Billy Gibbons and Sierra Ferrell on 2022’s raucous Dropout Boogie. And Auerbach’s co-op rock band, the Arcs, recorded two acclaimed albums and toured the world, while his second solo recording, 2017’s Waiting on a Song, was a spelunk into the heart of his adopted hometown Nashville’s studio history, drawing on a cross-generational cast of legendary session players. Then, there’s the guitarist’s football-field-long production credits, ranging from the Black Diamond Heavies to Dr. John and Grace Potter to La Luz to CeeLo Green to Marcus King to Hermanos Guitiérrez to Robert Finley and Yola.
“We got to this maturity as a band where not only can we call these friends, but we can deliver music our idols want to play on.”—Pat Carney
Sometimes, when you’re in the forest, all you can see are the trees. But now, after all that experience, the Black Keys’ omnivorous tastes, ceaseless drive, and undeniable success tilted their creative compass and comfort zone to Ohio Players, which might be poetically described as an album of peace, soul, and thunder. Also, eclectic and skillful af. Here, Auerbach and his drumming buddy have evolved what sounds like a mastery of every genre they’ve chosen to assimilate over the years: blues, jazz, country, classic pop, rock in its old and new variants, soul, hip-hop … even ambient music. Spend 20 minutes listening to the anthemic chords of “On the Game,” a co-write with Noel Gallagher; the fuzz fests “Paper Crown” and “Everytime You Leave,” the latter co-written with Beck; the psychedelic hip-hop-pop of “Candy and Her Friends;” and the period-perfect reworking of William Bell’s 1968 Stax hit “Forgot to Be Your Lover,” and you’ll get lost in the vibe—a happy time traveler through roots-informed music’s past and present.
The band’s new release was made at the same time as they were creating their last few albums, with Dan Auerbach and Pat Carney collecting the results of their collaboration wish list.
The album’s other spark plugs include hip-hop-beat brainiac and producer Dan the Automator; Memphis rap legends Juicy J (of Three 6 Mafia) and Lil Noid; producer/guitarist Angelo Petraglia, who’s made records with Kings of Leon and many others; and Nashville session hero Tom Bukovac, a truly estimable guitarist.
Of course, the biggest surprise is Gallagher, who co-wrote three rockers for Ohio Players, lending his patently anthemic touch. As it turns out, Gallagher is a big Black Keys fan, and in 2009, the duo were invited to open for his former band, Oasis. “But we were busy,” Carney says, “and they broke up.”
Despite a four-year hiatus from 2015 to 2019, the Black Keys stayed busy—even separately, during that break. They resumed making Black Keys albums in 2018, with ‘Let’s Rock’, and while they were creating its two successive releases, Auerbach and Carney also launched the series of collaborations that yielded Ohio Players.
“We had this epiphany—we can call our friends to help us make music,” Carney says. “It’s funny because we both write songs with other people, but we got to this maturity as a band where not only can we call these friends, but we can deliver music our idols want to play on.”“Noel Gallagher was feeling inspired because he hadn’t recorded like that. It’s not really common to have zero baffles between the vocals and the drums.”—Dan Auerbach
The first call was to Beck—a major influence on Auerbach and Carney when they were growing up in Akron. “His aesthetic was incredible,” Auerbach says. “He wore his influences on his sleeve, and we learned from that. There was someone showing us a way to go.” Beck was also an early Black Keys fan, and took them on tour in 2003. He is on half of Ohio Players’ 14 tracks as a writer, vocalist, guitarist, and keys player.“
After we’d gotten Beck in the studio, we were throwing names back and forth—‘Who else would be meaningful and write big songs we like?,’” says Auerbach. “Noel was at the top of the list.” The Keys’ manager, and even Gallagher’s team, when initially approached, responded that the former Oasis co-leader simply doesn’t co-write. “But we got a message back a few days later that said he’d be down if we came to London. We didn’t know if it was going to work, but after we recorded one song the first day, it took all our nervousness away.” By the end of a week, they had three numbers for Ohio Players.

“That was amazing on a lot of levels,” Auerbach continues. “It was fun as hell. We’d really wanted to go to Toe Rag Studios in London and record there. Toe Rag is such an amazing studio. It’s one room, no vocal booths or anything like that—smaller than a single-car garage. [The all-analog space is where Wolf Alice, Tame Impala, the Kills, James Hunter, Hugh Cornwell, and many others have recorded.] Pat’s got a drum kit, I’m on guitar, and Noel’s playing his ES-335 most of the time, with Leon Michaels on this weird little German ’60s keyboard, and [engineer] Liam Watson behind the old, beautiful desk.”
After the sessions, Auerbach and Carney dubbed Gallagher “the chord lord.” “He would sit there and cycle through chords until he found that one that worked with mine,” Auerbach recounts. The songs they cut, “On the Game,” “Only Love Matters,” and “You’ll Pay,” were essentially recorded live, with additions—like Bukovac’s guitar—done at Auerbach’s Easy Eye Sound studio in Nashville. “Every time we listened to a playback, it sounded so good that it was inspiring, and Noel was feeling inspired because he hadn’t recorded like that before. It’s not really common to have zero baffles between the vocals and the drums. We were just going for it.”
“I definitely tend to classic sounds, and then it’s nice to be able to move from there, finding new ways to use them.”—Dan Auerbach
If anything, collaborators like Gallagher and Beck have amplified the Black Keys’ already impressive way with hooks and choruses—reinforced as usual by Auerbach’s guitar, which, regardless of musical setting, always seems rooted in the tones of the ’60s and ’70s.
“I definitely tend to classic sounds,” he says, “and then it’s nice to be able to move from there, finding new ways to use them. But just being able to find that classic sound has always been thrilling. It’s finding the right fuzz pedal or finding the right combination of things that make that magic that’s on all of this stuff.”
On their most recent major tour, the Black Keys hit the road as a sextet. “Our band is so capable,” says Auerbach. “The guys that we’ve been touring with sing and play percussion and keyboards, so we can recreate anything, which is awesome.”

Fuzz has long been an important element of Auerbach’s sound, and it expands the dimensions of “Please Me (Till I’m Satisfied),” “Paper Crown,” and others. Auerbach primarily used three fuzz pedals on Ohio Players: an Analog Man Sun Face, Marshall SupaFuzz, and Fulltone Octafuzz—sometimes in combination, mostly driving a narrow-panel tweed Deluxe when he was on home turf at Easy Eye. But there’s plenty of sweet stuff in the grooves, too. In particular, the cover of “Forgot to Be Your Lover” enjoys not only a sweeping string arrangement but a lovely, chiming phase-shifted guitar that pairs perfectly with Auerbach’s near-falsetto vocal—another element of his singing that he’s perfected over time. (“My family would sing bluegrass, with all those falsetto parts, so it never felt out of the realm of possibility for me—although I never had the balls to do that until we made the Blakroc album, and we were messing around and experimenting,” he notes.) “Forgot to Be Your Lover” was done at Valentine Recording Studios in Los Angeles, a room frozen in time, left exactly as it was after its last remodeling in 1975—a place perfect for the track’s old-school vibe.
With its intuitive intersections of locations, collaborators, and the Black Keys’ realization of the strength of their own artistry, maybe there was some Zen at work during the Ohio Players sessions. And perhaps beyond. As we end our conversation, Auerbach offers an anecdote: “I was just making a record with Early James yesterday, in a friend’s hundred-plus-years-old home. As I was getting ready to record, my friend said, ‘Hey, I’ve got this guitar in a case here. Your friend dropped it off for you a couple years ago. He couldn’t get ahold of you or something.’ It was an old Supro Res-O-Glass that I had bought in Akron and completely forgotten about. I had loaned it to somebody 10 years ago. We took it out of the case. The strings on it were prehistoric, rusty, and we plugged it into a little black-panel Champ, and James played slide guitar on it, and it’s got a little Airline pickup. God! It sounded so amazing. And it was just like all kinds of wrong—hadn’t seen a luthier in a decade. You know what I mean? But it was the perfect thing for the sound that we were looking for. The perfect thing.”

On October 9, 2023, the Black Keys threw a blues party at Nashville’s Brooklyn Bowl, digging into their North Mississippi hill country sonic roots with Magnolia State ringers Kenny Brown on guitar and Eric Deaton on bass. Here, they play “Fireman Ring the Bell,” a variation on the “Rollin’ and Tumblin’” theme by the late R.L. Burnside.

PG’s John Bohlinger hung with Alter Bridge’s two-man guitar army, Mark Tremonti and Myles Kennedy, before their sold-out show at The Orpheum Theater in Memphis. Tremonti and Kennedy showcased some beautiful signature Paul Reed Smith guitars, as well as a not-yet-released PRS signature amp.
Thanks to techs Dave Pate and Scott Davis for their help with the details.

Brown Sound
Not surprisingly, Tremonti exclusively plays his Paul Reed Smith Mark Tremonti Signature.
The first is an early model from around 2002, sporting a signature brown burst with a tremolo bar. All guitars have D’Addario strings, though gauges vary by tuning. This one is tuned to Eb with 49–38– 28–17–13–10. Tremonti uses Dunlop Tortex 1.3 mm picks.
Spare Some Change?
This is Dime—short for Dimebag—Tremonti’s second PRS single-cut with a whammy bar.
Don't Call Me Daughter
This is Stella, named after Tremonti’s two-year old daughter. Tremonti and Paul Reed Smith came up with the body design together. PRS isn’t set up to mass-produce this shape, so there won’t be a wide-scale production.
Bearded Beauty
This “Fenton” graphic guitar is one of 20 produced. This was a 20th anniversary model with original art painted by Joe Fenton.
Outlaw Style
H.A. (Hell’s Angels) was the second prototype Tremonti signature made by PRS. The pickups are early prototypes.
Mark Tremonti's Pedalboard
Tremonti’s signal starts with an Evidence Audio ‘The Reveal’ cable from his guitar to his pedals, and Mogami W2319 and Square Plug SP5 plugs for patch cables. Pedals include a Morley “Mark Tremonti” Signature Wah, Ibanez TS808HW, Boss TU-3, Boss OC-5, Digitech The Drop, MXR Smart Gate, Mark Tremonti prototype signature chorus/vibrato, and a Lehle Little Lehle III true bypass loop pedal. There’s also a G-Lab SD-1 running into the amp’s effects loop.
The Big Reveal
The PRS MT 100 Mark Tremonti Signature 100-watt three-channel head has not been officially released yet, but Tremonti has been touring with it for a while, as a shake-down cruise.
Crushin' Cabs
He runs this tube-driven beast into two oversized Mesa 4x12 cabs, loaded with Celestion British V30s wired at 8 ohms. The amp uses a Kikusui PCR1000M voltage regulator/power conditioner, plus there’s a Lehle P-Split for splitting signals to main and backup heads.
The Four Horsemen
Kennedy tours with four of his new PRS Signature guitars. The ones finished in natural and white are both tuned to Eb or Eb with a dropped C#, depending on the song. The signature is a bolt neck, T-style guitar with 10” radius, and Narrowfield pickups. All guitars are strung with D’Addario Light Top/Heavy Bottom Strings (.010-.052).
Dr. Hoo
Kennedy reveres owls for their wisdom and adaptability. PRS has a long-standing tradition of using bird silhouettes for inlay markers, so it only made sense that Kennedy and PRS would incorporate their collective avis admiration in the signature model.
Green Machine
Kennedy’s green Signature is tuned to A#–G#–C#–F#–A–#D#, and G–#G–#C#–F#–A#–D#, depending on the song.
Back(up) In Black
Kennedy’s black Signature is strictly a backup in case there are problems with any of the others.
Diezel Power
Kennedy runs two Diezel heads: a Diezel VH4 and a Diezel Herbert. The amps run into two Diezel 4x12 cabs loaded with green Tone Tubby Hempcone 40/40 Ceramic speakers.
Myles Kennedy's Pedalboard
Kennedy runs his MXR Carbon Copy and an EarthQuaker Devices Dispatch Master in the VH4’s clean loop. Over on his pedalboard, there’s a Dunlop MC404 CAE Wah, Boss TU-2 tuner, Electro-Harmonix’s Nano POG, Lizard Queen, and Freeze, a Ceriatone Centura, Strymon Deco, Line 6 MM4, and a Boss RV-6.
