Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.48% — somewhat different

The MXR M267 Octavio Fuzz is a reissue of the Roger Mayer-designed Octavio octave fuzz pedal originally used by Jimi Hendrix, generating upper octave harmonics combined with fuzz saturation for the distinctive octave fuzz tones heard on Hendrix recordings including Crosstown Traffic and Purple Haze. The circuit uses a transformer to generate the octave-up harmonic overtone above the fuzz-saturated guitar signal. True bypass.
The Keeley Octa Psi is an octave fuzz pedal from Keeley Electronics delivering upper and lower octave fuzz saturation with a psychedelic, synth-like character suited to experimental and psychedelic rock. The circuit produces harmonically layered saturation with octave overtones that add otherworldly quality to guitar tones. Used for experimental, psych rock, and progressive guitar applications.
