Jackson Audio Silvertone Twin Trem
jackson.audio
Almost any effect can be used subliminally or to extremes. But tremolo is a little extra special when employed at its weirder limits. Unlike reverb or delay, for instance, which approximate phenomena heard in the natural world, tremolo from anything other than an amp or pedal tends to occur in the realm of altered states—suggesting the sexy, subterranean, and dreamy. Such moods can be conjured with any single tremolo. Put two together, though, and the simply sensual can be surreal. Modify this equation by mating two distinctly different tremolo types, and the possible sound pictures increase manifold.
The all-analog, U.S.-built Jackson Audio Silvertone Twin Trem accomplishes this by combining a syrupy harmonic tremolo—the likes of which you’d hear from an early-1960s brown-panel Fender amp—and an optical tremolo like that in a Silvertone 1484 Twin Twelve amp or black-panel Fender. Both effects can be used independently, but it’s when the two are blended that the Twin Trem shines.
Doppelganger Effect
The Twin Trem’s optical and harmonic circuits are obviously not identical twins, but each is operated via its own 3-knob array consisting of speed, depth, and a smaller volume knob that will boost or cut the output of the individual circuit. Both tremolo types modulate at speeds slower than what you hear in amplifier equivalents. I don’t have a Silvertone Twin Twelve tremolo on hand for comparison. But the slowest speed from a mid-1960s Fender optical tremolo matched the rate of the Twin Trem’s optical circuit at about the midpoint of its range. At its slowest, the optical side will cycle through minimum and maximum volume in just a little under a full second, which feels molasses-slow, stretching and enhancing the ramping effect. Maximum speeds on the Twin Trem are closer to the maximum on the old Fender. But that’s still a pretty rapid modulation rate and the Twin Trem’s range-y depth controls make fast modulations sound extra alien.
If you’re sensitive to such things, the dedicated volume controls are great for overcoming the perceived volume drop that goes with any tremolo. There’s much more gain available than what you need for that purpose, and slathering on the volume gives the pulses a burly quality that’s tough but can obscure some nuance. The ability to create disparate volumes for each circuit means you can slightly foreground one tremolo type or the other, opening up an even wider tone palette and highlighting unique interrelationships between modulations.
Double Shots Make Dizzy Daze
The Twin Trem’s optical tremolo side (if you open up the back you can watch the pulsing diode that activates the opto-resistor) exhibits the throbbing tendencies one associates with black-panel Fender amplifiers. In fact, the Twin Trem sounds uncannily like the old Vibrolux I used for this test, but with more speed, range, and intensity. On its own, it’s a convincing stand-in for a 1960s Fender, Gibson, or Silvertone circuit.
One of the coolest things about the harmonic tremolo is how it often doesn’t sound like tremolo at all. In a harmonic tremolo circuit, high and low-frequency bands are split and volume-attenuated out of phase from each other, creating a bubblegum elasticity in the modulations. At slow speeds the harmonic tremolo’s phasey attributes take center stage (clip 1). And though the modulation texture is less swirling than what a simple phaser produces, the more vowel-like pulses lend a sleepy, mysterious aura to the modulation.
Though I did not use the pedal in stereo, I did utilize the effects loop, inserting a delay between the harmonic and optical tremolo, creating a little extra wash in the harmonic tremolo sweeps (clip 2). You can go crazy with possibilities here: How about inserting a multiple-tape-head-style delay for maximum syncopated mayhem? But the most traditional application for the effects loop is to simulate the reverb-into-tremolo order found in many mid-1960s amps. Again, it’s a great option when you need ’60s reverb/tremolo combo amp vibes and there’s no such animal around.Clip 2, which showcases the Twin Trem’s effects loop, also captures the two tremolos working together. And even at this fast-twitching speed you can hear the phaser-like wash softening the front end of the harder optical pulses that are situated downstream. Some dual-trem settings can produce chaos. But the best ones are thick, eerie, and propulsive in ways that can completely transform a song’s ambience.
The Verdict
The Twin Trem is just short of 300 bucks, and it’s easy to rationalize such a significant expense when you consider that you get two distinct tremolo sounds that you can mix, match, and switch between very readily. Maximizing the investment probably requires a little extra thirst for the unusual. Not all combined settings are money. Some rhythmic syncopations will drive you batty, and without the benefit of digital control you can disappear down little rabbit holes trying to find an elusive, perfect subdivision between modulation tempos or replicating a texture you found the previous week. These are very minor traps, however. In general, the Twin Trem is forgiving and easy to use. And if you get in a meditative place with the pedal, and let it do the driving from time to time, the riffs will practically write themselves.

The iconic alt-rock duo leans on floor modelers to execute their carefully choreographed live shows.
Along with contemporaries like MGMT and Passion Pit, Greenwich, New York, duo Phantogram’s experiments crosspollinating hip-hop, indie, and punk rock helped cement and elevate a new era of electronic-influenced alt-rock and indie music. At the start of the 2010s, you’d be hard-pressed to find a college radio station or dorm-room playlist that didn’t include a Phantogram hit.
Sixteen years after the release of their debut record, band leaders Josh Carter and Sarah Barthel, who started Phantogram in a town of just a few thousand people, are touring behind their latest full-length, 2024’s Memory of a Day. The tour included a sold-out stop at Nashville’s Ryman Auditorium—a different sort of barn than the kind they used to perform in back in Greenwich—where PG’s John Bohlinger caught up with Carter and Barthel. Courtesy of some help from their tech, the duo showed us how they’re pulling off their theatrical live experience.

Music Mantogram
Carter is endorsed by Ernie Ball Music Man guitars, so all three of his road axes are variations on his current favorite Cutlass model. This one, first among the trio, is finished in black with a gold pickguard, and like its stablemates, it bears the Phantogram logo inlaid on the first fret. Carter removes the vibrato bar and uses his hand to pull the bridge up to nail the warbles. Aside from that, this one is all stock, and strung with Ernie Ball Paradigm .010s. While he sometimes grabs a pick, Carter plays most of the set with an acrylic nail on his index finger.
Brown Sound
This first backup Cutlass is finished in brown with the woodgrain peeking through and a burgundy tortoiseshell pickguard. It has a Seymour Duncan single-coil-sized humbucker in the bridge position for a hotter output than its black counterpart.
Step It Up
This natural finish Cutlass has had the same pickup mod as the brown one, but this one stays tuned a half-step up for special deployment.
Clean Business
Carter uses a wireless system to run to this Neural DSP Quad Cortex at his feet. His tech has set it up to emulate many of the pedals Carter uses in the studio. Carter appreciates the tactile and flexible nature of the system; it can take MIDI programming so Carter can focus on performing, or it can be rigged up to function like a traditional pedalboard. He uses a mix of amp emulations, including AC30-, 5150-, Fender tweed-, and Jazz Chorus-style patches.
A Boss volume and expression pedal alongside the Quad Cortex give Carter some extra control over the setup.
Josh Carter's Pedalboard Playground
While Carter carried a compact stomp station for tour, he’s addicted to stompboxes and uses them for inspiration when writing and sound building during studio sessions. Here’s what a small selection shared from his collection:
“The most prominent pedals I used for years onstage before switching to the Quad Cortex were the Line 6 DL4, Electro-Harmonix Holy Grail, Boss
DD-6 Digital Delay, Boss OC-3 Super Octave OC-3, Fulltone OCD, Wampler Ego Compressor, and Route 66 American Overdrive.
My go-to studio pedals are the MXR Joshua Ambient Echo, Line 6 DL4, Death By Audio Reverberation Machine, Electro-Harmonix Holy Grail, Chase Bliss Generation Loss MkII, Chase Bliss Mood MkII, Boss DD-500 Digital Delay, Chase Bliss Audio Automatone CXM 1978, Old Blood Noise Mondegreen Delay and Reflector Chorus.
And some honorable mentions for pedals I’ve been really digging as of late would be the Neon Egg Planetarium, Roland Space Echo, and various vintage & new spring reverbs.
Silver Stunner
Sarah Barthel initially played keys in Phantogram, but she learned bass and mimicked her synth parts on the instrument so she could move about freely and interact more with Carter. This custom-made sparkle-finish Fender Mustang is the perfect size for her, and she just recently started playing it with a pick. She runs into a Quad Cortex, too, but the Fender Bassman stack lurking behind the bass serves as an onstage monitor.
Jazzmaster
Barthel isn’t confined to the bass, either. At some points in the set she jumps onto this prized Jazzmaster, which she’s had for 15 years.

Fuzz can be savored in so many ways. It can be smooth. It can be an agent of chaos. But it can also be a trap. In service of mayhem, it can be a mere noise crutch. Smooth, classy, “tasty” fuzz, meanwhile, can lead to dull solos crafted as Olympian demonstrations of sustain. To touch the soulful, rowdy essence of fuzz, it’s good to find one that never lets you get quite comfortable. The EarthQuaker Devices Gary, a two-headed distortion/overdrive and rabid, envelope-controlled square-wave fuzz designed with IDLES’ Lee Kiernan, is a gain device in this vein.
Gary is not exclusively a destruction machine. Its distortion/overdrive section is a very streamlined take on EarthQuaker’s Gray Channel, a versatile DOD 250-derived double distortion. Like any good circuit of the 250 ilk, Gary’s hard clipping OD/distortion section bites viciously in the high- and high-mid frequencies, supported by a tight, punchy low-mid output. You can play anything from balanced M.O.R. studio crunch to unhinged feedback leads with this side of Gary. But it’s the envelope-triggered pulse-width fuzz—which most of us will hear as a gated fuzz, in many instances—that gives the Gary its werewolf duality. Though practice yields performance patterns that change depending on the instrument and effects you use around the Gary, its fuzz ultimately sputters and collapses into nothingness—especially when you throw a few pitch bends its way. The cut to silence can be jarring, but also compels a player to explore more rhythmic leads and choppy riffs that would sound like sludge with a Big Muff. The Gary’s unpredictable side means it won’t be for everybody, but its ability to span delicioso distortion and riotous splatter fuzz in a single unit is impressive.

For anyone serious about mixing their own recordings, it’s a tool worth considering.
In the world of music production, the tools we choose profoundly influence the final sound of our recordings. I want to make the case for adding one tool that is rarely, if ever, in the “must have” or “sexy gear” spotlight but can deliver huge results to your mixes: the console summing mixer. Tighten up your belts—the Dojo is now open.
While digital audio workstations (DAWs) have revolutionized music production, offering unparalleled editing and flexibility, many producers, including me, still mix back into an analog console for the sonic character and three-dimensionality that it imparts. But buying a professional console isn’t cheap! This is where console summing boxes come into play, offering a unique way to enhance your mixes and elevate them to a professional level.
How Does It Work?
Very simply put, recording consoles have two basic sections: an input section (all the channels of mic pres, and EQ) and a center section (that sums all of the channels together and routes those signals to various configurable outputs such as inserts and aux buses). A console summing mixer is essentially the center section of a console and is designed to sum the individual audio channels, aux buses, stems, and submixes from your DAW in an analog domain.
In a DAW, digital summing—the process of combining multiple tracks and buses into a stereo mix—is handled through complex binary algorithms that, while precise, can sometimes lead to a mix that feels lifeless and one-dimensional, lacking the warmth, depth, and cohesion that analog consoles impart.
One of the most significant advantages of using a summing box is the introduction of harmonic distortion, a natural byproduct of analog circuitry. This isn’t like amp or pedal distortion, but rather a subtle harmonic saturation that adds richness and character to the sound. Low-end frequencies gain girth and definition, while high frequencies have a smooth, silky quality. You can achieve natural compression through subtle variations in phase and amplitude, but that depends on how hard you push the summing mixer box.
But the best benefit, in my opinion, is its ability to produce an undeniably open stereo image. Digital summing, while accurate, often lacks dimension or a sense of space. Analog summing introduces subtle variations in phase and amplitude, creating a sense of width and depth that makes each instrument feel like it occupies its own space in a more 3-D stereo field, which results in a more engaging and polished mix. I’ve also found summing boxes encourage a more deliberate and thoughtful approach to mixing, as it requires submixing certain elements.
API’s ASM164 ($3,195 street) is wildly flexible, offering VU meters, multiple inserts, two separate stereo mix options, and more.
For those who work “in-the-box” and aren’t in the market for a summing box, let alone a console, incorporating a summing box can also serve as a valuable learning tool. By running stems through a summing box and comparing the results to an entirely digital mix, you can train your ear to recognize the subtle qualities that make a mix feel warm, cohesive, spatial, and dynamic. This heightened awareness can then inform your in-the-box mixing decisions, even when you’re not using a summing box.
“Whether you want to add depth and dimension to your tracks, enhance your stereo image, or bring a touch of analog magic to your mixes, a summing box can be a gamechanger."
It’s important to choose the right summing box for your needs and budget, as different models offer varying sonic characteristics. Good summing mixers typically start around $2,000, such as Rupert Neve Design’s 5057 Orbit Summing Mixer. While more expensive, API’s ASM164 ($3,195 street) is wildly flexible, offering VU meters, multiple inserts, two separate stereo mix options, and more. The key here is to understand your needs.
Pairing a summing box with high-quality outboard processors, such as compressors or EQs, will allow you to shape your mix in ways that are impossible within a purely digital setup.
Whether you want to add depth and dimension to your tracks, enhance your stereo image, or bring a touch of analog magic to your mixes, a summing box can be a gamechanger. For anyone serious about mixing, it’s a tool worth considering—one that can make the difference between a mix that’s good and one that’s truly exceptional. Until next month, namaste
