Originally launched in 2017, the F-Octave makes its triumphant return to the Diamond lineup with its signature high-gain silicon fuzz, paying homage to the iconic Foxx Tone Machine of the 1970s. The F-Octave embodies the spirit of fuzz, delivering raw, expressive tones that are truly one of a kind.

At its heart, the F-Octave is a finely tuned, discrete analogue fuzz circuit designed to inspire with rich harmonic content and dynamic response. It's simple and intuitive layout honours the essence of classic stompboxes while providing the flexibility to shape your sound and unleash your creativity.

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 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.
