Fulltone SUPA-wah

A "Boosted" Clyde Wah: The DNA of 60s Vox, Fulltone Style

The Supa-Wah follows the lineage of Fulltone's beloved "Clyde" wahs, themselves inspired by the legendary 60s Vox Clyde McCoy pedals. The idea is simple: to recapture the vocal quality, dynamics, and "alive" feel of the best vintage wahs, while adding genuinely useful options for a modern pedalboard. Hence the addition of two extra modes, Phat and Sub, which extend the range toward thicker, deeper, and even more expressive sounds.

In terms of design, Fulltone goes into great detail: a hand-wound MU-80 inductor (with MuMetal shielding to reduce noise), a FWP-2 potentiometer with a "vintage" feel and long lifespan, and a steel chassis designed to block as much interference as possible. The result: a wah that sounds "old school," but with the stability and consistency worthy of heavy use in both studio and live settings.

For Which Musicians and Styles?

The Fulltone Supa-Wah targets guitarists seeking an expressive wah that adapts to multiple contexts without switching pedals: edgy blues, classic rock, rhythmic funk, stoner, fusion, or even modern leads with high-gain amps. Thanks to its very distinct modes, it shifts from a round, vocal sweep to higher, sharper positions perfect for cutting through a mix.

The Sub mode is particularly deep, making the Supa-Wah an excellent candidate for bass (or for guitarists tuned low): it delivers a wide, almost "synth-like" effect in places, without losing control underfoot. Live, the built-in booster can help you stand out on solos; in the studio, the Input Level adjustment is ideal for dialing in aggressiveness and harmonic richness depending on the take.

Controls, Modes, and Design: Made for the Modern Pedalboard

At the core of the experience is a 5-position rotary selector that changes the wah's character: Sub, Wacked, Phat, Jimi, and Shaft. Each mode reorients the frequency range and sweep feel to suit a specific use. The Input Level potentiometer acts as an attack control: set low, the circuit remains very clean and "hi-fi"; set higher, you push the input and gain more grit, bite, and harmonics.

On the side, a switch activates the JFET Buffer/Booster. In practice, this is a real advantage if you place the wah before a crowded pedalboard or play through a high-gain amp: the signal retains its presence, interaction with the chain is more stable, and you can even boost the level up to +20 dB for lead passages. Finally, the Fulltone rocker offers a longer sweep than many traditional wahs, with micro-adjustable nylon pivot points to tailor the feel (softer, firmer, more "precise") according to your playing style.

The Sound

The Supa-Wah stands out with a very pronounced vocal quality and a particularly dynamic response: it finely reacts to right-hand attack, nuances, and how you "push" the pedal underfoot. The Jimi mode targets the typical grain and range of 60s wahs, with that round yet incisive character that works wonderfully on crunch and vintage fuzz tones. Shaft raises the wah range for sharper, funkier rhythms that snap and carve the groove.

The two additions really make a difference: Phat is more "singing," with generous mids and a throat-like sensation (perfect for expressive leads), while Sub goes lower, with impressive depth and expressiveness ideal for heavy chords, bass, or low-tuned riffs. The Wacked mode emphasizes a wider, more massive wah, very effective for rock and psychedelic sounds. Thanks to the shielding (MuMetal, steel chassis, grounding strap), the pedal maintains excellent noise and interference rejection, a crucial point for a wah often placed at the start of the chain.
