The first entry in Friedman Amplification’s much-anticipated Vintage Collection is the Plex, a painstakingly crafted homage to Dave Friedman’s own 1968 JMP Super Lead plexi—the archetype and foundation on which the entireFriedman lineup is based.
Any working ’60s JMP Super Lead is an amazing amplifier, but the combination of Dave’s ears, experience, and quality time with his own Super Lead add up to a melding of twists and tradition that captures the richness, power, and dynamics of Marshall non-master-volume amps in a high-quality and, if you want, quieter package.
Stripped Down, Lowdown, Bright, and Brighter
True to lineage, the 50-watt Plex uses a pair of EL34 power tubes and a trio of 12AX7s pulling preamp and phase inverter duties. The familiar volume 1, volume 2, presence, bass, and mid knobs handle gain and EQ tasks. But the Plex deviates from tradition, too. An old Marshall Super Lead has four inputs—high and low sensitivity inputs for channel I and II. The Plex, however, uses a single pair of inputs that are hardwired in jumpered fashion—the same way you might jumper on the front panel of a 2-channel Marshall—effectively mixing the two preamp stages. A post-phase-inverter master volume helps keep the sound pressure level in check when you need to cool it without compromising feel and dynamics. And above each volume knob is a 3-way bright switch. The switches alter the frequency and gain response of the corresponding volume control, toggling between a darker bypassed setting, a mild treble boost enabled by a 100 pF bright capacitor, or a screaming third setting with a 4700 pF cap in the line. The power switch doubles as a high/low voltage selector, engaging an internal Variac that drops operational voltage from 120 volts to 90 volts, achieving the brown sound synonymous with ’80s hard-rock Super Lead applications.
The spartan back panel sports outputs for 4-, 8-, or 16-ohm loads and an IEC mains power input. The head weighs in at a reasonable 34 pounds with dimensions of 24" x 10" x 8.75"—just a hair smaller than a real JMP. The circuit is arrayed on a high-quality printed circuit board—a manufacturing method Friedman favors in many respects for quality control purposes.
But … Does It Van Halen?
Hell yes it does. Dime the Plex, flip it to low voltage, and you’re living in the Eddie zone. Recreating that high-octane, modded-Marshall aggression and kerrang with the most familiar Marshall-style knobs is easy and intuitive. But this amp is full of surprises, too, and many sonic possibilities hide behind the simple additional controls.
The lead channel, controlled by volume 1, is aggressive and edgy, capturing the cut and midrange growl most immediately associated with vintage plexis. Anything below 3 on the gain control is pretty clean. At around 4, hot pickups will induce breakup. And in the 5-to-6 range, it comes alive with rich saturation, enhanced harmonics, and sustain. Approaching 10, the Friedman blossoms into something furious and snarling. The 100 pF bright capacitor setting gently lifts the top end for a hint of jangle, while the 4700 pF cap boosts upper midrange and treble, adding even more chimey range and sharper bite.
The normal channel, controlled by volume 2, feels very much like the antithesis of the lead channel. It’s dark and brooding with lots of resonance in the bass. Keeping the gain below 5 still yields a woolly, forceful voice. Starting around 6 it slips into thick clipping, and as you move toward 10, the Friedman delivers progressively denser tonalities, more compression, and more sustain. The 100 pF bright cap mode adds a splash of air, while the 4700 pF setting significantly jacks the drive and boosts frequencies from 1200 Hz up. Each is a very different version of a cool color.
Sonic Structure
Much of the amp’s tone-shaping flexibility comes from using the volume knobs, not just for gain, but as tone controls to create a best match for a specific guitar. In a general sense, the normal channel adds fullness and body to single-coils, while the lead channel brings definition, bite, and clarity to humbuckers. With a Stratocaster, setting both channel volumes in the 3-to-6 range achieves classic Marshall clean that hints at Hendrix. Strat pickups sound zingy with bright caps bypassed, but the 100 pF setting adds even more attractive shimmer. Lead mode and high gain settings are a nice fit for a Strat, too. Setting the lead channel to 7-to-8 and backing the normal channel to 4 pushes the amp to full-bodied, blistering sustain, and adding the 4700 pF bright cap adds upper midrange urgency. P-90s in a Les Paul Jr. are a more extreme version of this recipe—gritty, snarling, and explosive. But if I ever sensed the signal was lacking, just rolling up the normal channel and using the 100 pF cap did the trick—evoking, more than once, the gritty style of the Pixies’ Joey Santiago.
The Plex’sdynamics and touch sensitivity are outstanding. Using just variation in guitar volume and picking intensity, I effortlessly moved from clean arpeggios to crunch and full-on shred. The low sensitivity input felt especially nice for working with these intensity adjustments, too. It predictably reduces gain, but it also darkens and mellows edgier pickups. The vintage-voiced tone stack is sensitive as well. Treble, mid, bass, and presence controls are accommodating, cover a lot of harmonic range, and even extreme EQ settings never seem to neuter the fundamental voice. If you use pedals, you’ll run them straight into the front of the amp. There’s no effects loop here. Still, a Riveter Electric Brass Tacks treble booster with dark amp settings conjured the sounds of early Sabbath, and the front end easily handled the extra level.
My Kid’s Asleep
Usually, implementing a master volume in this type of circuit can produce sonic anemia at low levels. But Dave Friedman’s addition of a unique post-phase-inverter master volume means you can preserve much more tone, character, and feel at tiny-venue levels. The low-voltage Variac mode offers interesting less-hot options, too, enabling spongier, more saturated, creamier tones at less deafening volumes.
The Verdict
The Plex offers a perfect balance of vintage Marshall-ness and a not-too-busy list of practical extra features—maintaining the essence of plexi tone while expanding tone-shaping functionality and increasing the amp’s useful volume range. But for all its enhancements, the Plex stays close to its vintage inspiration, giving it a brash, raw, unruliness that’s always exciting

Dojo Columnist Bryran Clark at the helm.
The idea is that multiple small improvements over time will produce big results. Legendary British cycling coach Dave Brailsford called this “the aggregation of marginal gains.” His strategy was simple: Focus on getting one percent better in every area related to riding a bike. Within 10 years, the British cycling team went on 178 World Championship races and won five Tour de France victories and over 60 Olympic gold medals. Kaizen, indeed! I’m still amazed when I get sessions from other engineers who have no color-coded recording session tracks, haphazard organization within the session itself, and haven’t saved multiple versions. These are three problems that are easily solved with a bit of kaizen. Tighten up your belts, the Dojo is now open.
Color differentiation reduces your cognitive load and allows for faster, more efficient recording, editing, mixing, and overall session management.
Diversify Your Color Palette
Color-coding recording session tracks is a powerful tool for visual organization. It’s an essential, non-technical practice that can significantly enhance workflow efficiency and track management. In a typical modern recording session, there can be between 30 and 100 tracks, each representing different instruments, vocals, effects, and other elements. Without a clear organizational strategy, navigating through these tracks can become overwhelming and time-consuming.
By assigning specific colors to different types of tracks, producers and engineers can quickly identify and locate the tracks they need to work on, so establish a consistent color scheme for types of instruments.
Here’s mine:
• Drums are always slate blue.
• Guitars are various shades of green because they’re made from trees (of course, almost everything else is, too, but both guitar and green share the same first letter).
• Bass instruments are always brown (because they’re powerful and can make you brown your trousers).
• Synths and keys are various hues of purple (I think of Prince and “Purple Rain”).
• Vocals are always yellow because when you get lost in the stifling dark caverns of your mix and can’t find your way out, focus on the vocals—they will lead you toward the light.
An example of our columnist’s strict session color coding in his DAW.
Regardless of your choices, color differentiation reduces your cognitive load and allows for faster, more efficient recording, editing, mixing, and overall session management. Moreover, color coding helps in identifying groups of tracks that need to be processed together, such as a drum bus or background vocals, thus making it easier to apply group processing and adjustments.
Your layout of a recording session is another critical factor for maintaining organized and productive workflows. A well-structured session layout ensures that all elements of the recording are easily accessible and logically arranged. My tracks have a consistent order: drums at the top, followed by bass, guitars, keyboards, vocals, and effects. There’s no right way to do this, but whatever you do, be consistent.
“I have an existential map. It has 'You are here' written all over it.” – Steven Wright
Consistency helps individual producers and engineers to work more efficiently, but also facilitates collaboration with others. When multiple people are involved in a project, establish a standardized layout that will allow everyone to quickly understand the session structure, find specific tracks, and contribute without confusion. Also, a clear layout helps minimize mistakes during recording, editing, and mixing, like possibly overlooking important tracks or processing the wrong ones.

“Waste Not, Want Not”
One of the most important things to always remember is to immediately save a new version the very first time you open a project or session. That way, if something happens, and it will eventually (I’ve even had session data get corrupted on that specific sector of the hard drive), you’ve left the original session alone. Every time you work on the song, or project, save a new version. This practice safeguards the process and ensures project security.
This is also important during the creative phase when trying out different ideas and arrangements. If a new idea doesn't work out, it's easy to revert to a previous version without losing valuable progress. Furthermore, saving versions at critical milestones—such as after recording, editing, and mixing—provides fallback options in case of technical issues or unexpected problems. And lastly, saving versions creates a chronological historical record of the session's development, which is invaluable for reviewing the evolution of the track, project, or entire record!
We can agree that Jerry Garcia’s playing pulled from all directions of the American musical experience to create an unparalleled playing vocabulary that persisted not only at the forefront of the Grateful Dead’s music, where he was most prominent, but also in his solo work with Jerry Garcia Band and in his bluegrass collaborations. Throughout the Dead’s rambling career, the band shapeshifted through various eras, often with very different musical values, giving fan lots to disagree about. What’s the essential stuff? Where should new listeners go to get acquainted before going into live-tape-land? And just how influential were the Dead on modern music?
Grace Bowers has quickly won a reputation for high-energy guitar heroics.
While she appreciates the sentiment, Bowers doesn’t love being called a guitar prodigy, saying it dismisses the eight years she’s put into studying the instrument.

“I was living in California at the time, in a small town outside of San Francisco,” she reflects. “And there’s absolutely no live music there, whatsoever. I didn’t even know any people my age who played an instrument. So, I pretty much had no hope. And I would always dream that I’d be playing on a stage, or just anywhere, honestly. It always felt super unrealistic and like, ‘Oh, that would never happen.’”
When the pandemic hit, the now 18-year-old Bowers was finishing the seventh grade, and the abrupt separation from her peers didn’t exactly help to improve her sense of belonging. Pretty soon, however, things took a major, positive turn: “I started posting videos online, and it got some momentum,” she shares. Gibson took notice, and offered her an endorsement when she was just 14. Then,“We moved to Nashville, and I was playing onstage almost every night.”
The sudden wealth of opportunity that came with the move changed everything. “It was the biggest motivation ever,” she continues. “Made me want to do it more than I ever have [laughs].”

By now, Bowers’ résumé has gathered more than just moss. Earlier this year, she was recruited by Dolly Parton to perform on Dolly Parton’s Pet Gala; she’s played with Devon Allman, Tyler Childers, Christone “Kingfish” Ingram, and Susan Tedeschi; and in August, shared a bill with her first guitar hero, Slash. And, on the tails of all this success, she’s just released her debut album, Wine on Venus.
Produced by John Osborne of the Brothers Osborne, the album is a collection of eight original tracks, written by Bowers in collaboration with her band the Hodge Podge, and one cover—Sly & the Family Stone’s “Dance to the Music.” Although she has been playing for nine years, the grasp Bowers has on her instrument at 18 is rare. She knows just what notes to play and when to play them, saying very much with very little. She also wields a tone that’s just fuzzy enough, just singing enough, and just wailing enough—when she feels like it. Wine on Venus is the perfect showcase of her wisdom on guitar, antecedent to her being even a quarter century of age. It was recorded live in the studio over the span of one week, and Bowers knew going in just which shots she was going to call.
The eight original songs on Wine on Venus were written by Bowers in collaboration with Esther Okai-Tetteh and the rest of her band, the Hodge Podge.
She shares that she’s highly averse to recording in an isolated booth, unable to see the rest of the band—something she’s done a lot as a session guitarist. “Before we went into the studio, I told John, if I’m wearing headphones, it’s over,” she says. “And when we’re playing live, eye contact is one of the most important things. So, the band was live in the room, and then I was outside looking through a window in the control room with John. We put my amp upstairs on this balcony—it’s like a house, the studio—and turned it to 10, and for the entire record, my guitar was recorded in the control room. It was very loud; I’ll tell you that.”
Carving out your own voice as an individual artist in improv-based genres can be a significant challenge, and Bowers kept that in mind. “I’d say [that difficulty comes from] oversaturation. There’s a lot of jam bands out there right now. And don’t get me wrong; I love that kind of music, but what a lot of them lack is songs. When we went into the studio, I wanted to make sure that we wrote songs and didn’t just jam. I was very intentional in the writing process with Esther [Okai-Tetteh, vocalist]—to write catchy hooks and make sure that the lyrics meant something.”
Okai-Tetteh, whose first name is pronounced “Acey,” was Bowers’ primary writing partner in the development of the album’s material. “A lot of it [came together] sitting on my bedroom floor, writing songs every night. She wrote a lot of the [vocal] melody, which is where I struggle. Whereas I wrote all of the music, and then we both collaborated on the lyrics.” The other members of the Hodge Podge, who include keyboardist Joshua Blaylock, drummer Brandon Combs, bassist Eric Fortaleza, and co-guitarist Prince Parker, each fleshed out the arrangements with their own contributions.
Bowers picked up guitar at age 9 after discovering Slash, and fully fell in love with it at 13, after hearing B.B. King for the first time.

Blues guitarists are typically working with the starkest templates (three or four chords) and the most concise vocabulary (the minor pentatonic scale), which, in many albeit honest, dedicated hands, often sound commonplace. But in the best hands, the blues can be some of the most powerful music out there. As Bowers puts it, “The blues comes from your heart, and you’re not just playing it, if that makes sense. I’m not the best at expressing emotions.... It comes out better for me on guitar.”
“As long as I have a very clean-toned amp and my pedalboard, I’m pretty much good to go.”
Bowers owns three different SGs, and her two main choices are her ’61 model with P-90s—“That’s like my baby”—and a newer model with humbuckers. Her pedalboard is a “basic setup,” and she doesn’t know all the names of her pedals off the top of her head. But in classic funk fashion, she does like to employ her wah while playing rhythm parts. As for amps for live shows, she doesn’t yet have her own tour bus, so she’s been relying on backlines. “As long as I have a very clean-toned amp and my pedalboard, I’m pretty much good to go,” she says. Her greatest inspirations on guitar, aside from Slash, are Leslie West, Eddie Hazel, Carlos Santana, and Marc Bolan. “I have a huge Electric Warrior poster above my bed right now,” she tells me.
As for the future, Bowers says she doesn’t really have long-term goals, exactly. “I don’t like to set expectations for myself, because I just want to see where things are going to bring me naturally. I love doing what feels right in the moment.
“Before, I was super shy and didn’t have a lot of confidence,” she continues. “Guitar really helped me build that up, and now I’m doing things that I would have been horrified to do three years ago. It’s definitely helped me come out of my shell.”
