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

Duane Betts enjoys a control set modification that was preferred by his father, the late, legendary Dickey Betts.
Guest Picker - Duane Betts
Betts’ 1961 ES-335 has its toggle and volume-dial positions switched.
A: My favorite mod is the one on my 1961 Gibson ES-335. The toggle switch and neck volume knob positions have been switched so the volume knob is more accessible for volume swells using your pinky finger. This is something my dad had done when he obtained the guitar in the ’90s as he loved using the volume swell effect.
A pedal primed for vintage fuzz sounds.
Obsession: My current obsession is this DanDrive Secret Machine fuzz that JD Simo gave me a few years ago. I don’t use fuzz often but I’ve loved it as a way to change things up and give the listener something fresh. My normal tone is very natural with the amp turned up. This is just a great fuzz tone that gives me a new angle that I really enjoy pursuing both live and in the studio.
Reader of the Month - Steve Nowicki
A: A push/pull knob for humbucker coil split. It’s a sneaky little mod I throw on my tone pots. You won’t get amazing Strat tone, but the ability to instantly swap between Les Paul chunk and Fender twang during a jam opens a ton of possibilities tonally. Plus, no extra switches or routing needed—even though it’s fun to hack guitars apart.
Obsession: The EVH 5150 Iconic EL34 amp. Owning an 80-watt half-stack in a Brooklyn apartment might be overkill, but damn this amp is awesome. It delivers insane amounts of gain and distortion, yet every little nuance of your playing comes through crystal clear. I pair it with a Bugera Power Soak so I can crank the head and get that warm “Brown Sound” tone at lower volumes.

John Bohlinger and his Lukather-ized Strat.
A: I’ve hacked up a bunch of guitars over the years, but my favorite mod remains the highly intrusive, expensive, and quixotic B-bender install. It is the equivalent of open heart surgery, and there’s no going back—but the first time you play the Clarence White “You Ain’t Goin’ Nowhere” intro right, it’s totally worth it.
John at work. When it comes to mods, he know the drill!
Obsession: I recently filmed a PG video where we swapped pickups in my ’90s Strat with an EMG Lukather set. I never thought I’d go active, but what gets me is how smoothly the volume and tone work. I’m rethinking all my gear biases. Like maybe there’s been some progress since 1957.

Let it bleed: Jon dials back the treble on his Tele.
A: Installing a treble bleed on my volume pots has changed how I play electric guitar. Previously, I never dialed back my volume knob because it dulled my sound. Now I can fine-tune loudness and gain while retaining tone—it’s a game changer. I still swap pickups and hardware, but one mod always comes first: the humble treble bleed.
Did you know both John Paul Jones and Jimmy Page played on Shirley Bassey’s iconic recording of “Goldfinger?”
Obsession: John Paul Jones. I’ve always loved his bass (and other instrumental contributions) with Led Zeppelin. But after seeing the Zep documentary [Becoming Led Zeppelin] I searched his session work from 1964–1968, which includes Shirley Bassey, Lulu, Donovan and more. What an amazingly versatile and talented artist he is!
With Is, My Morning Jacket turned to an outside producer, Brendan O’Brien, who has worked with Pearl Jam, Stone Temple Pilots, and many others.
Their latest album, Is, represents not just a continuation of the rebirth that began with 2021’s self-titled effort, but a profound evolution in their creative process: Currently, MMJ—which also includes guitarist Carl Broemel, bassist Tom Blankenship, keyboardist Bo Koster, and drummer Patrick Hallahan—find themselves in the midst of what Broemel characterizes as a “special and interesting era,” one marked by newfound inner peace, a willingness to relinquish control, and, as James simply puts it, “the freedom to do whatever the fuck we want,” that has resulted in some of their most focused and dynamic work to date.
Is emerges as the product of this revitalized My Morning Jacket, distilled from a wealth of material that James had accumulated, throwing “every single idea into the pot,” he says, rather than reserving some for solo projects as he’d done in the past. The result is both concentrated and adventurous, a tightly focused 10-song collection that still, in characteristic MMJ fashion, roams freely across stylistic boundaries. From the soaring leadoff track “Out in the Open,” a sort of rootsy take on U2’s widescreen anthem rock, to the evocative and soulful first single “Time Waited,” the heavy-riffing “Squid Ink” to the hypnotic psych-folk workout “Beginning From the Ending,” the lilting, harmony-laden pop nugget “I Can Hear Your Love” to the ominous minor-key prowl “River Road,” the album covers vast musical territory. “Jim has a giant archive of song ideas and it’s always growing,” Broemel says, and then laughs. “I think it’s the good and the bad thing about having a digital recording device in your hand at all times—you can capture every idea. So we had so much to work through.”

But Is also marks something of a letting go for James, who, for the first time in years, welcomed an outside producer into the fold. And not just any producer, but capital-P producer Brendan O’Brien, whose extensive resume spans music’s biggest names, from Pearl Jam, Stone Temple Pilots, and Rage Against the Machine to Bruce Springsteen, Neil Young, and AC/DC. For James, who had long acted as the band’s producer in an effort to “play all the positions myself,” this surrender of control was unusual. As for why they went with O’Brien, James says, “The thing that really struck me about Brendan was once I started playing him demos, he immediately had ideas and opinions that were really constructive without making it about his ego. He’s really great about telling you, ‘Ah, I don’t think this song’s as good as the rest.’ Or, ‘I don’t really like this chorus, what if we replaced it with something else?’ He was just always about the song.”
Adds Broemel, “He managed to pull us out of us, if that makes sense.”
“I think it’s the good and the bad thing about having a digital recording device in your hand at all times—you can capture every idea.” - Carl Broemel
To be sure, many of these songs both took shape and transformed in the studio. “I Can Hear Your Love” and “Beginning From the Ending,” for example, evolved from solo recordings with drum programming and sound effects into fuller band arrangements. But perhaps the most dramatic metamorphosis was “Out in the Open.” The song originated during the pandemic as a ukulele riff that James found so complex he “couldn’t even play it,” and that he eventually arranged into what he calls “kind of a ballad.” It sat for a couple years before he brought it to the band during these sessions. “When we listened to it, everybody had the same feeling as I did: ‘We like the riff, but where does it go? What does it do?’” James recalls. O’Brien provided the breakthrough. “He said, ‘What if we turn this into a rock song? Bring in the electric guitar, amp it up, and keep it getting bigger?’” The final version blends James’ original ukulele recording with a full-band, big-rock arrangement—what he describes as “a really cool merging of the unknown inspired by Brendan.”

This anything-goes mindset extended to the band’s approach to guitars and amplification. While James and Broemel brought their recent arsenal—including James’ Fender Princeton amp, his Gibson ES-335 signature model, a Gibson ES-355 prototype “that Gibson made me when we were first figuring out my guitar that I use a lot in the studio,” and his custom Reuben Cox plywood T-style guitar, alongside Broemel’s treasured 1988 Bigsby-equipped Les Paul Standard and Duesenberg Starplayer TV—O’Brien’s studio offered what Broemel describes as “a disgusting amount of amazing guitars.” The amp selection was equally impressive, running the gamut of Fender classics (“the brown amps, the black amps, the silver amps,” as Broemel puts it) along with discoveries like a Port City head that became a frequent go-to. Rather than being fussy about gear choices, the band found themselves drawn to whatever served the song best. “Half the time I wound up with one of Brendan’s SGs in my hand through one of Brendan’s amps,” James recalls. “I used to be more precious about it, but now I really just don’t give a shit at all, as long as it sounds right with the song.” This approach yielded particularly dramatic results on “Die For It,” where Broemel created a massive guitar solo by positioning two amps—“a Super Reverb and something else,” he says—in the middle of the room, capturing what he calls a “giant stereo thing that’s so wide and washed-out and crazy, kind of like what it feels like at our shows.”
“Half the time I wound up with one of Brendan’s SGs in my hand through one of Brendan’s amps.” - Jim James
It’s this sort of liberation from old habits that has helped recharge the band after almost three decades together. Although, James admits, “It ebbs and flows. There’s been periods where it’s been very easy and periods where it’s been very difficult.” Is reflects this hard-won wisdom; its title speaks to the fact that the music “just is what it is,” James says. “The record always makes itself. You really have to let go.”

It’s a perspective that has enabled My Morning Jacket to find a path forward. As Broemel notes, “In some ways, all we want to be is like a brand-new band again, but that’s impossible. So we’ve just gotta keep going.” One thing that never changes, he adds, “is that the feeling of playing a good show never gets old. It’s like catching a huge fish. That’s evergreen for me.”
James agrees, noting that the band has never sounded better. “Music’s infinite,” he says. “We’ll never exhaust all the possibilities. As long as you’re trying something new, that’s what keeps it fun and fresh, hopefully for us and for the listener.”
