More than seven decades on, tremolo remains one of the most mesmerizingly delicious and mysterious textures in music. And while it's now a familiar part of the popular music lexicon, it has lost none of its power to evoke mystery, oceanic depths, faraway lands, and deep space.
Harmonic tremolo is perhaps the most mysterious tremolo of all. Rather than use volume attenuation to achieve its hypnotic pulses, harmonic tremolo uses dual band filtering and LFOs to emphasize high and low frequencies in a rhythmic, alternating pattern. The resulting effect is, generally speaking, woozier than the stuttery textures of amplitude tremolo—and capable of suggesting and inducing very dreamy states of mind.
Fender Telecaster into Delta II, black panel Fender Tremolux head, and Universal Audio OX tweed Deluxe cabinet emulation. All modulation and filtering are manipulated and generated via the Delta II.
Harmonic tremolo emulations are relatively plentiful these days, but few are as fun and capable of spanning old-school sounds and twisted textures as Spaceman's new Delta II. It generates the deep, woozy, pitch-stretching modulations that make early-'60s-style harmonic tremolo so fundamentally appealing. It can also stretch the effect to extremes with little likeness to tremolo at all.
A Deep Weave
The Delta II walks the line between complexity and simplicity adroitly. The interactive nature of Delta II's controls might frustrate players used to fast, predictable results from one of two knobs. But it's worth investing the time to grok how they work together, because those relationships can be the ticket to very distinct and individual variations on harmonic and amplitude tremolo.
Even the two most recognizable controls on the Delta II—the depth and rate—behave in comparatively unusual ways. Much of the first third of the depth's range, for instance, is subtle enough to be imperceptible at certain settings. The rate knob, meanwhile, hits the maximum modulation rate of a Fender amp tremolo before you even get to the 12 o'clock position, and at extremes it pulsates at rates so fast that it sounds more like ring-modulated fuzz than tremolo. On some pedals, these expansive parameter ranges might be annoying, but the Delta II's precise pots make it easy to find sweet and familiar settings.
The small lower left knob called lag enhances the Delta II's flexibility considerably. It shifts the phase relationship between LFO outputs. At full counterclockwise, the two outputs are in phase and produce less phase-y amplitude-tremolo-style pulses. As you twist it clockwise, the phase relationship changes—inducing ever wobblier variations on the harmonic tremolo flavor. It's a smart addition for players who occasionally like the directness of amplitude tremolo.
At extremes, it pulsates at rates so fast that it sounds more like ring-modulated fuzz than tremolo.
Even more tone variations are available via the 3-position voice switch. In the left position, the LFO modulates the high-frequency and dry signals. In the middle, it modulates high and low frequency signals. And in the right position it modulates the low-frequency and dry signals. The latter two of these tend to sound the most immersive, while the high-and-dry settings tend to sound a touch thinner and more focused.
All three of these voices can be recast depending on how you use the resonant filter (regulated by the "freq" control) and the resonance knob. And much of the real magic in Delta II's control layout is down to how effectively the frequency, voice, and resonance controls work together as a very powerful EQ section. In the studio—or as you refine a live band mix or arrangement for a given song—you can use various combinations of these controls to carve out very specific harmonic spaces. And given how deep these tremolo throbs can be, the ability to effectively emphasize a frequency band here and cut another there opens up many arrangement possibilities. Once you master the practice of fine tuning them, you can make tremolo pulses more integrated or distinct within the sound of instruments occupying a given frequency range.
The Verdict
Billing the Delta II as a harmonic tremolo nearly undersells what the pedal can do. Apart from generating liquid modulations that would tickle any brown-panel Fender or Magnatone fan, the Delta II can dish synthy ring-modulated chirps, rotary speaker-like colors, and snorkely filtered pulses. Studio hounds will be thrilled with how the frequency, resonance, and voice controls enable surgical sculpting of trem tones so they can be situated in very specific harmonic spaces.
The Delta II isn't without its quirks. You can easily go down a rabbit hole searching for ideal EQ, filter, and resonance profiles. But it takes just a modicum of practice to get a lot of extra mileage out of those controls, and they are full of surprises. If you're looking for classic harmonic tremolo formulas exclusively, there are more direct and inexpensive ways to get there. For more curious tremolo fans, however, the Delta II is a treasure chest of sweet, deep, and demented modulations that can be fantastically transportive.

J Mascis is well known for his legendary feats of volume.
J Mascis is well known for his legendary feats of volume. Just check out a photo of his rig to see an intimidating wall of amps pointed directly at the Dinosaur Jr. leader’s head. And though his loudness permeates all that he does and has helped cement his reputation, there’s a lot more to his playing.
On this episode of 100 Guitarists, we’re looking at each phase of the trio’s long career. How many pedals does J use to get his sound? What’s his best documented use of a flanger? How does his version of “Maggot Brain” (recorded with bassist Mike Watt) compare to Eddie Hazel’s? And were you as surprised as we were when Fender released a J Mascis signature Tele?
Editorial Director Ted Drozdowski’s current favorite noisemakers.
Premier Guitar’s edit staff shares their favorite fuzz units and how and when they use them.
Premier Guitar’s editors use their favorite fuzz pedals in countless ways. At any point during our waking hours, one of us could be turned on, plugged in, and fuzzed out—chasing a Sabbath riff, tracking menacing drone ambience, fire-branding a solo break with a psychedelic blast, or something else altogether more deranged. As any PGreader knows, there are nearly infinite paths to these destinations and almost as many fuzz boxes to travel with. Germanium, silicon, 2-transistor, 4-transistor, 6-transistor, octave, multimode, modern, and caveman-stupid: Almost all of these fuzz types are represented among our own faves, which are presented here as inspiration, and launch pads for your own rocket rides to the Fuzz-o-sphere.

My favorite is my Burns Buzz, a stomp custom-made for me by Gary Kibler of Big Knob Pedals. Gary specializes in recreations of old circuits, and this Burns Buzzaround-inspired box has four germanium NOS transistors and sounds beautifully gnarly. It improves on the original, which Robert Fripp favored in early King Crimson, by adding a volume control. I went a little stir-crazy acquiring fuzzes during Covid lockdown and now have an embarrassing amount. My other current darlings are a SoloDallas Orbiter (which balances fuzz with core-signal clarity), a Joe Gore Duh (a no-nonsense, 1-knob dirt shoveler), and my Big Knob Tone Blender MkII 66, which taught me how smooth and creamy fuzz can be with carefully calibrated settings. These pedals allow me to cover all of my favorite fuzz sounds from the past 60 years. I do have one more secret weapon fuzz that only travels to the studio: an original Maestro FZ-1 that I picked up used for about $20 in the early ’90s. It’s banged up but functional, takes two 9V batteries, and is righteously juicy.

The two greatest fuzzes I’ve ever played are a Pigdog Tone Bender build and a Paul Trombetta Bone Machine. Both experiences will stick with me for decades to come. But creations by those two masters of fuzz come with a price tag high enough to keep my time with those pedals fleeting.
Instead, my favorite fuzz is an inexpensive, mass-produced pedal that hasn’t left my board since I reviewed and subsequently purchased it in 2021: the Electro-Harmonix Ripped Speaker, designed to emulate the distorted tones on ’50s and ’60s records that were created with broken or misused gear.
Retro inspiration is not all it has to offer though. The rip knob, which controls transistor bias, is the star of the show, interacting with the fuzz level to deliver everything from a smooth, mild fuzz to sputtery mayhem that can evoke a faulty channel strip or old tube combo that’s been set ablaze. I prefer to crank the rip knob and feed it to a phaser and slapback analog delay, which gives me a bit-crushed-like gnarliness. Pull back on the rip or add a boost in front of the pedal, and it has a more organic but still gated sound, which, for me, can be just the thing to set my sound apart in a more traditional setting.
For a cool $116, the Ripped Speaker, which seems to fly under most fuzz freaks’ radars, might be the special something that complements the rest of your board or just a tone you turn to on occasion. Either way, it’s a great deal.

You could give me the most powerful-sounding fuzz in the world, but if it was in a stupid-looking enclosure, I don’t know if I’d give it a second look. This is just how we operate: Vision is the sense we privilege most, even in matters of audio.
Luckily, the most seismic, monstrous fuzz I’ve ever heard also happens to come in a beautiful package. The Mile End Effects Kollaps, built by Justin Cober in Montreal, measures an elephantine 7 3/8" x 4 5/8" x 1 1/2", and its MuTron-meets-’60s-Soviet aesthetic matches the sounds its guts produce. The Kollaps is modeled after the nasty Univox Super-Fuzz circuit, and carries a few of that pedal’s hallmarks, including its use of germanium diodes and midrange boost control. Cober added a switchable Baxandall active EQ circuit, with up to 12 dB of boost and cut to both low and high frequencies. Coupled with the mid-boost toggle, this gives the Kollaps a shockingly broad range of tonality to play with.With the mids off, the Kollaps is jagged and ruthless, a deafening turbojet of upper mids and chest-vibrating lows that yanks me toward the darker, less commercially successful corners of ’90s doom and noise rock. Kicking on the EQ circuit and boosting the lows turns it titanic. With the balance (volume) and expand (gain) controls maxed, the Kollaps starts to live up to its name, crumbling into a thick, overextended chaos in a way more polite fuzz circuits rarely do.
My favorite Kollaps sounds occur when the mids are engaged, for an articulate, deeply textured fuzz sound that retains your attack. Playing with your guitar’s volume knob, you can coax a range of EQ profiles and take advantage of the upper- and lower-octave content in the fuzz. With guitar volume lower, you can access some unbelievably emotive and sensitive sounds that still teeter on the edge of chaos and violence. It’s a rich, volatile circuit that gets as close as I’ve heard to a sound and physical feeling I’d call “planet-destroying.”

My first fuzz, A Sovtek Big Muff, remains tied for first place among many favorites. The pedal’s most famous virtues—corpulence and sustain—are among the reasons I treasure it. But the way the Sovtek pairs with a Rickenbacker 330 and Fender Jaguar, which were once my two primary guitars for performance and recording, made it invaluable in various projects for a long time. Neither the Ricky nor the Jag are sustain machines, but the wailing mass of theBig Muff makes their focused voices an asset—inspiring tight, concise fuzz phrases, hooks, and riffs as well as articulate chords.
A silicon Fuzzrite clone built by good pal Jesse Trbovich (long-time member ofKurt Vile’s Violators) runs second place to the Sovtek in terms of tenure, and is a very different fuzz. It’s a piercing, hyper-buzzy thing, but a perfect match for a squishy 1960s Fender Bassman head and 2x12 I adore. Perversely, I sometimes couple it with a Death By Audio Thee Ffuzz Warr Overload or Wattson FY-6 Shin-Ei Super-Fuzz clone. These tandems create chaos and chance, but sing loud and melodiously too—at least when I’m not intentionally bathing in feedback. The Jext Telez Buzz Tone, a clone of the mid-’60s Selmer circuit, is often my go-to now. It’s a low-gain affair compared to the other fuzzes here, and I use it in its even-lower-gain (and vintage-correct) 3-volt setting. It’s pretty noisy, but it is thick, dynamic, detailed, raunchy, and plenty trashy when the occasion demands it. It’s also a very cool overdrive when you back off the gas.Jason Shadrick - Managing Editor
I rarely need fuzz in my everyday gigs, but it's one of the most fun effects to explore when I'm noodling around. At a NAMM show a few years ago I plugged into Mythos' Argo and as soon as I hit a note my eyes lit up. The sound of the fuzz wasn't unwieldy or hard to manage. It gave me the illusion of control while the octave was the magic dust on top. I knew right then I wasn't leaving the show without one. After I spent some time with it, I became enamored by how much more the Argo can do.
It's inspired by the Prescription Electronics C.O.B. (Clean Octave Blend), so the control set is similar. The octave is always present in the signal path, but you can dial it out with the blend knob. The fuzz and volume knobs are self explanatory, but dialing the fuzz and octave knobs all the way down gives you a killer boost pedal. I find my favorite settings are at the extremes of the fuzz and blend ranges. Typically, both are either all the way up or all the way down. Another great experiment is to turn the fuzz down and then pair it with a separate drive pedal. And in octave mode, Argo is one of those pedals that inspires you to head directly for the neck pickup and stay above the 12th fret.
Grez Guitars has introduced the Grez GrandTour Bass, a short scale semi-hollow carve-top instrument available in 4-string format.
The Grez Grand Tour Bass, designed in collaboration with bass powerhouse Ian MartinAllison is, like all Grez instruments, a modern sleek interpretation of the classic instruments from the 50’s and 60’s.
The instruments feature a carved Spruce top, Honduran Mahogany body and neck. The 30" scale construction includes a Macassar ebony fretboard, 12” radius with 21 jumbofrets. Each bass comes equipped with a Halon bridge, Grez string anchor and LaBellaDeep Talkin’ long scale 45-105 flatwound strings. Electronics include Curtis Novak Bisonic/Darkstar pickups with coil tap.
The Grand Tour bass features a nitro finish and is available in a variety of colors(pictured here in custom Toasted Marshmallow).
Grez Grand Tour Bass with Ian Martin Allison
Barry Grzebik explains: “I love process of design instruments, marrying acoustical,electrical, visual and ergonomic engineering with industrial and artistic design. In this case creating something that artfully balances the desire for a robust acoustic voice with the need to hold up to professional touring and stadium stage volumes. One small notable detail is that although this is a short scale instrument, because of the after-length of string past the bridge, it uses standard long scale strings which dramatically increases sting options and availability.”
Ian Marin Allison shares, “I’m inspired by the unique character of vintage hollow andsemi-hollow basses, but they don’t always live up to our modern expectation of stability, playability, versatility and QUALITY. I’m proud to have helped create something that does”.
The Grez Grand Tour Bass, is available now from Grez Guitars and their dealers with astreet price starting at $5,999. Light customization is welcome with delivery times aslittle as 8 weeks.
