Diamond F-Octave – Classic Fuzz, Reinvented with an Octave Snarl
Originally introduced in 2017, the F-Octave returns with a vengeance—delivering bold, high-gain silicon fuzz rooted in the legacy of the legendary Foxx Tone Machine. This updated version preserves the raw energy of the original while offering expanded control and flexibility for modern players.
At the heart of the F-Octave lies a discrete analog circuit with two distinct personalities. With the octave mode engaged, it produces screaming upper harmonics and a snarling, synth-like edge that slices through any mix. Switch the octave off, and you're met with a thick, saturated fuzz full of chewy midrange and vintage-style compression—perfect for riffs, chords, and searing lead tones.
Tone shaping is simple but powerful. The LPF and TONE controls let you sculpt the top end to your liking, from smooth and rounded to aggressive and cutting. The octave effect shines especially on single notes and double-stops above the 12th fret, but the magic really happens when you experiment—heavy chords trigger unpredictable overtones, while bent notes produce shifting, multi-octave textures that evolve as you play.
Whether you're chasing garage grit, vintage psychedelia, or modern doom saturation, the F-Octave delivers with touch-sensitive dynamics and a wide gain range. Roll your guitar’s volume back for sputtering breakup, or dime everything for full-blown fuzz chaos. The circuit is equally at home on guitar or bass, making it a versatile tool for any rig.
This is fuzz in its most expressive form—dynamic, harmonically rich, and full of attitude.
