Originally launched in 2017, the F-Octave returns to the lineup with its signature high-gain silicon fuzz, crafted in tribute to the legendary Foxx Tone Machine. First heard in the early '70s, that iconic pedal earned its place in the fuzz hall of fame with its biting saturation, chewy sustain, and unmistakable octave-up grind. The F-Octave picks up where that legacy left off—delivering raw, expressive tones with a character all its own.

At its heart is a finely tuned, discrete analog fuzz circuit designed for rich harmonic content and dynamic response. The layout is simple and intuitive, staying true to the spirit of classic stompboxes, but with added flexibility to shape your sound. Engage the octave mode to unlock searing, upper-register harmonics that cut through any mix with vintage attitude and synth-like texture. Switch it off, and you're greeted with a warm, fat fuzz—full of wooly midrange and smooth compression, perfect for leads, chords, or riff-driven grooves.

This is fuzz the way it used to be: bold, unpredictable, and endlessly fun. Plug in, switch on the octave, and rediscover why fuzz never went out of style.
