Originally released in 2017, the F-Octave has been revived as a tribute to the legendary Foxx Tone Machine, featuring its signature high-gain silicon fuzz. It faithfully reproduces rich harmonic saturation, growling octave-up tones, and vintage character. This discrete analog circuit produces two different fuzz sounds. With Octave ON, you get a fuzz with synth-like cutting and screaming harmonics, while with Octave OFF, you get a fat, warm fuzz with a classic feel and sustain. Shape your tone with the TONE and LPF controls. Emphasize the treble for a crisper sound, or suppress it for a more pleasant tone, creating the perfect sound for any situation. The octave effect works on single notes, chords, and harmonics, adding a wild texture and higher harmonics, responding dynamically to your playing. The F-Octave is perfectly suited for both guitar and bass, and is ideal for sounds across all genres, including vintage psychedelia, garage grit, and modern doom.Condition: No problems with use.
