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 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, psychedelic rock, and progressive playing contexts. The octave fuzz circuit produces harmonically layered saturation with octave overtones that add a complex, otherworldly quality to guitar tones. Keeley's American production quality underpins the Octa Psi's circuit design.
The Tru-Fi Octavia Fuzz is based on the rare Tycobrahe Octavia, itself part of the same octave-fuzz family Jimi Hendrix used on tracks like Purple Haze, and reproduces that aggressive upper-octave fuzz character. A negative 9V circuit runs on a standard negative-tip 9V power supply, and a switch lets players disable the octave effect entirely for a straightforward vintage 1970s fuzz tone. The level and boost controls interact to create a range of usable tonal sweet spots rather than a single fixed voicing. Reviewers highlight its accuracy in recreating Hendrix-associated upper-octave fuzz tones, citing strong results on songs like Who Knows. Suited to psychedelic rock and blues-rock players chasing authentic vintage octave-fuzz textures.
