In 1987, Mike Soldano created the SLO-100, a fire-breathing amp that, to this day, remains influential to those who build modern high-gain amps. Though the amp arrived at the peak of the hair-metal age, the SLO-100 appealed to players in many styles. Dokken’s George Lynch and Eddie Van Halen used it, but so did Mark Knopfler. That versatility is a big part of what made it iconic.
Decades later, the SLO-100 remains legendary. But at just south of $4,000 for a new one, they are not cheap. So, it’s cool that Soldano distilled so much of the essence of the SLO-100 into the SLO Pedal, a stompbox that sells for a mere $229. It’s a pretty nice stand-in for a player that doesn’t have the real deal on hand.
Streamlining Again
Several years back, Soldano released the Supercharger G.T.O., which essentially offered the preamp section of the SLO-100 in a pedal equipped with two 12AX7 tubes. I have an early edition of the Supercharger G.T.O., and it is, indeed, fantastic. It’s also pretty big. While it’s a very different stomp, the SLO Pedal is much more compact and practical in many respects. It’s built around a more straightforward, tubeless design. It also uses much of the gain section topology from the SLO-100.
While the SLO Pedal lacks the independent overdrive controls for preamp and master that you see on the SLO-100, Soldano users will recognize the 3-band EQ, presence control, and side-mounted deep switch, which stands in for the SLO-100’s depth knob and adds low-end oomph. It’s an easy-to-read and streamlined set of controls. And though it might look complex to a 3-knob-overdrive type of user, it’s easy to work with.
Hot-Rodded Hellraiser
When the SLO Pedal arrived on my doorstep, all the knobs were dialed to 7 (approximately 1:00 on a clock). Taking that as a lucky omen, I plugged it in, and right off the bat, without any adjustments, it sounded fantastic.
As much as I might have been inclined to play the SLO Pedal forever at lucky 7s, it offers many, many more tone-shaping possibilities. Just engaging the deep switch takes the edge off the highs and adds more body. Set this way, it almost walks the line between amp-style drive and woolly fuzz. When I adjusted the EQ to get a darker, creamier lead sound, I was pleasantly surprised at how easy it was to bring extra clarity in and out of the blend in precise amounts. Darker sounds also don’t seem to squash dynamic range in the way other drive pedals might. There’s less discernible compression and, even at a fairly dark setting, pick attack tends to cut through.
I was similarly impressed that the pedal didn’t squeal out of control at maximum-gain settings. It was also dead quiet when I muted the strings. In general, I probably wouldn’t use that level of saturation, but the way the SLO Pedal holds it together in that zone is impressive. There’s also a ton of clean headroom available. And even with the volume knob around 1 it was plenty loud.
SLO-Hand Stylings
Soldano amps were, of course, also used by very non-metal players, like Eric Clapton and Mike Landau, and the SLO Pedal shines in this context, too. With the gain rolled all the way off and the pedal volume cranked hard, the SLO Pedal delivers mid-gain sounds with a rich, overdriven amp feel. And though it might sound weird, I enjoyed the SLO Pedal’s lower gain sounds so much that, at times, I longed for even less than what I got at the minimum gain setting. I’m sure Soldano didn’t imagine this pedal as a boost. But with so much mid- to high-gain range, it’s hard to not imagine how a few cleaner sounds could make this a complete drive solution.
The Verdict
There are many other factors that give an amp its sound and feel, and Soldano nailed a lot of intangibles when they built the SLO-100 amp. But the way the SLO Pedal captures the personality of the SLO-100 is impressive. And even if you’re not specifically looking for the SLO-100 sound, the SLO Pedal can add a lot of that mid- to high-gain, with the headroom to get it across.

Art Tube Mp Project Series Tube Microphone/Instrument Preamp
Designed in Rochester NY and originally released in 1995, the Tube MP is celebrating its 30th anniversary in 2025.
The Tube MP/C is the most fully-featured member of the Tube MP family, designed for recording guitarists and bassists. It is a tube mic preamp and instrument DI with advanced features including an optical compressor/limiter and switchable line/instrument output levels for use as a re-amping device.

“They treated me like a kid, man,” he continues. “They really put me through the paces. There was a lot of hazing, and there was some tough love on a lot of those nights.”
Metzger estimates he left it all on the John & Peter’s stage hundreds of times, forming an old-school style of musical apprenticeship that can be heard in his playing today, three decades later. In any of the improv-heavy settings where he tends to find himself—such as his collaborative trio, LaMP, with members of the Trey Anastasio Band, the transformative Grateful Dead tribute Joe Russo’s Almost Dead, or in freelance situations—Metzger takes the patient and complementary approach of someone playing the long game. He’s a supportive and colorful collaborator who, to make a baseball analogy, always seems to have a good read on the musical ball, equally adept as a finely attuned rhythm player or commanding lead voice. For that, he offers a lot of credit to those early days.

“I kept my mouth shut and my eyes open,” Metzger explains, “and I learned what it takes to become a good, competent guitarist and what it means to have a distinct voice—Dean Ween has one of the most distinct lead guitar voices in rock ’n’ roll as far as I’m concerned. But not only that, also how to support a singer, and how to play a song, and when not to solo, which is just as important as knowing when to.”
Metzger remembers his early teen years, learning tunes by the Ramones—his first concert—and Jersey’s own Misfits, and getting turned ontoHendrix bootlegs and Boredoms records at New Hope’s Now and Then shop. Later, Melchiondo expanded his psychedelic worldview, hipping him to P-Funk— specificallyEddie Hazel’s guitar work—and theAllman Brothers.

It wasn’t long until Metzger put all those early lessons to work on the road. At 19, he was playing with his experimental trio F-Hole at Princeton, New Jersey’s Small World coffee when Phish guitaristTrey Anastasio wandered in. “As soon as we get done playing,” Metzger recalls, “he makes a beeline to me and basically started interrogating me about who I was listening to and what I was into gear wise and what kind of guitarists I was into. What I didn't realize was that he was basically auditioning me in real time to be in his friend Tom Marshall's band, who writes all the lyrics for Phish and was putting together a band at the time.”
Metzger scored the gig with Marshall’s Amfibian, playing sold-out shows on the road and opening him up to a whole new musical world. “I wasn’t that familiar with Phish at all,” he points out. “But I knew I liked being up in front of all those people and being able to just play all night. I was really kind of a focal point of the band, and that was my introduction to what is now considered the jam band scene.”
Fast-forward to the present: Metzger is a formidable member of the jam scene. He’s led and collaborated on a host of projects, including WOLF!, with bassist Jon Shaw and drummer Taylor Floreth; the blazing country-swing trio Showdown Kids, with his wife, violinist Katie Jacoby, and guitarist Simon Kafka; and his resplendent, forward-thinking 2022 acoustic-focused solo record, Too Close to Reason. In 2013, he teamed up with his longtime pal drummer Joe Russo, along with guitarist Tom Hamilton Jr., bassist Dave Dreiwitz, and keyboardist Marco Benevento, in forming Joe Russo’s Almost Dead. Colloquially known as JRAD, the group, in a sea of reverence, treats the Grateful Dead’s songbook almost as if it’s an edition of the Real Book—the shorthand jazz-standards tome—cracking open the large catalog and infusing their own voices with every improv-heavy performance.

Being a part of a Dead tribute act was never part of Metzger’s plan. In fact, he says he wasn’t all that familiar with the band’s catalog. “I wasn’t sure I was the right guy for the band,” he says. But with exploration and personal vocabulary so paramount in JRAD, Russo knew Metzger was the right guitarist for the job.
“You have to be willing to get in there and do your thing and make your mark unapologetically,” Metzger muses. “That's something that's made us stand out in a world of bands that are playing those songs.”
JRAD has developed a large, dedicated following, rising to the top of the Dead tribute scene. “The size of the audience that we have is mind blowing,” Metzger points out, “and the fact that the audiences are willing to go to the places musically with us that we take it, it almost feels like we're testing how much we can get away with a lot of the time.”

These days, JRAD makes up about half of Metzger’s current gig commitments, and LaMP fills the other. The trio was formed one night in 2018 at Burlington, Vermont’s jam nexus Nectar’s, when the guitarist joined forces with keyboardist Ray Paczkowski and drummer Russ Lawton, both longtime members of Trey Anastasio’s solo band, who also work as the psych-funk duo Soul Monde. “Right off the bat, there was a chemistry that was going to work,” Metzger recalls. “Those two guys are kind of celebrities up in Burlington, so it’s like doing a gig with the mayor or something. The whole town came out to see us, the place was packed, and I think it was very clear to everybody there that night, including us, that it would be a crime not to do it again.”
LaMP builds on the long history of the organ-trio tradition, referencing ’60s ensembles helmed by Grant Green and George Benson, the Meters’ soulful funk, more modern jammers like Medeski, Martin & Wood—and most notably their late-night groove collabs with guitarist John Scofield—as well as thrill-seeking, forward-leaning groups like John Abercrombie’s Gateway Trio and Tony Williams’ Lifetime, all while embracing the spirit of rock ’n’ roll abandon. As unabashed and freewheeling as that might suggest, Metzger and company shoot for a tasteful sonic experience more than a barn-burning blast-off, and at the fore of the band’s sound is a shared improvisational language built upon close listening just as much as any influence. “The real thing that we’re focusing on,” Metzger shares, “is having a good feel, a group sound, and some catchy melodies. Those things are enough to carry the thing without having to worry about ripping some blazing solos every song.”
This year, LaMP released One of Us, the follow-up to their self-titled 2020 debut. It’s filled with live-off-the-floor energy, or as Metzger puts it, “fresh tension.” The mostly first and second takes heard on the record, with barely any overdubs, successfully capture the band’s collaborative heart, making One of Us a ferociously spirited listen from beginning to end. “I like records that are made really quickly on low budgets with the clock ticking,” Metzger conveys. “You can feel that a little bit on the record. It’s not too polished. It's like you can feel that it’s three guys in a room playing together.”
LaMP’s One of Uscaptures the band’s effervescence with a set of mostly live-off-the-floor first and second takes.
Throughout One of Us, Metzger showcases his deep fluency in the Telecaster vernacular. With his Creston T-style, a chambered all-black affair loaded with Lollar P-90s, he slings lyrical licks that offer nods to the masters of the form, all the way back to the first Tele virtuoso, Jimmy Bryant through aces Roy Buchanan, Danny Gatton, Jim Campilongo, and Steve Cropper’s deep pocket. (In JRAD, Metzger calls on a Ronin Songbird loaded with DeArmond gold-foils, but his vocab and approach remain much the same.)
Metzger’s take on the tradition is less virtuosic gunslinger than most of those maestros, instead favoring a more complementary approach with an ear toward supporting the group. To that end, he keeps his sound mostly on the cleaner end by reserving a load of potential sonic energy. “I crank the amp,” he says, pointing out he prefers to set his combo—either a Victoria 35210, a 2x10 Fender tweed Super copy, for LaMP, or a Headstrong Verbrovibe 1x15, a replica of a 1963 Fender Vibroverb, which he favors for JRAD—to 7 or 8 so it’s fully opened up. A self-described “minimalist pedal guy,” he keeps four punch-packing pedals—a Bearfoot Putting Green compressor, Benson Germanium Fuzz, Paul Cochrane Timmy, and an Interstellar Audio Machines Octonaut Hyperdrive—on at all times. As hairy as that may suggest, Metzger maintains clarity, he explains, by keeping his guitar volume set between just two and four. That means that when he wants, he’s just a crank of the volume knob away from a wide-open, full-throated sound.

His approach to pedals says much about Metzger’s playing style in general. There’s always a load of possibility on reserve, and you can sense it. He’s not one to frequently lay sonic waste with a technical assault, but, rather, a massive map of potential musical avenues is perpetually close at hand, with his ear in the driver’s seat.
Listen to Metzger in just about any situation, whether as a bandleader, bandmember, or just sitting in, and there’s an obvious musical set of ethics in place—and it’s probably been in effect since his early days at John & Peter’s. The responsibilities are something like work hard, support others, be ready to deliver at all times, and, maybe above all, be yourself.
“I was told in no uncertain terms,” he recalls, “that the important thing about being a musician was to find your own thing. You’ve got to stand on your own feet. The ultimate goal that we’re all still working on is to sing our own song with our own voice.”
