F-OCTAVE – Vintage Octave Fuzz
Originally launched in 2017, the F-Octave returns to the Diamond lineup with its signature high-gain silicon fuzz, crafted in tribute to the legendary Foxx Tone Machine of the 70s. The F-Octave picks up the fuzz legacy delivering raw, expressive tones with a character all its own.
At its heart F-Octave 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.

Taking the lively, high-fidelity gain stages of the Comp/EQ, the Boost/EQ offers plenty of punch while maintaining clarity and transparency. While the Tilt and Mid controls give you complete freedom to sculpt your tone. Need more sparkle? Dial it in with the Tilt knob. Looking for a midrange boost to cut through your solos? The Mid control has you covered. Want to make your Marshall tone a bit more Fender-esque? It’s all possible with Diamond’s Boost/EQ.
In addition, the Boost/EQ features a second mode that provides a low-gain overdrive – transparent, yet full of character. This makes the Boost/EQ the ultimate Swiss Army knife for your pedalboard, combining clean boost, tone shaping and overdrive, into one powerful and versatile pedal.
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 woolly midrange and smooth compression, perfect for leads, chords, or riff-driven grooves.
Shape the sound of your fuzz with the LPF and TONE knobs and highlight the upper octave. Start with the LPF fully clockwise and the TONE control at noon for a balanced foundation. From there, tweak the TONE control to emphasize your ideal frequency – counterclockwise for warmer or darker tones, clockwise for a brighter fuzz, and adjust the LPF to smooth out and refine your tone to perfection.
The F-Octave’s octave-up effect shines with single notes, delivering killer tones that cut through – especially above the 12th fret. Break new ground by using it for heavy chording, creating gnarly random overtones as the octave circuit searches for the root note. Double-stop bends produce a twisted multi-octave sound, with the high octave climbing while a subtle sub-octave slowly drops in pitch. Switch off the octave for a more straightforward fuzz.
The F-Octave plays beautifully with both guitar and bass, making it a versatile tool whether you’re chasing stoner rock saturation, garage grit, or classic psych tones. Roll your volume back and explore everything from sputtery breakup to thick sustain. Crank it, and it howls.
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.
