The ultimate combination of Pitch-Shifter, Octave Generator, and analog Fuzz!
Imagine having your favorite pitch-shifter, octave generator, and analog fuzz all in one pedal.
A dual effect designed to inspire musical adventuring—that’s what the Keeley Octa Psi Transfigurating Fuzz is all about!
This all-analog fuzz and distortion pedal features a powerful transistor design that makes any guitar or bass pickup sound massive.
The fast-tracking polyphonic pitch-shifter offers a symphony of sounds to explore. Drop tuning, unique pitch-shifting combinations, and even chorus-inspired textures—this pedal goes far beyond standard fuzz or octave effects.
The Octa Psi allows you to switch the effects order on the fly, engage an all-wet mode, and toggle between True Bypass and Buffered Bypass. You can even plug in an expression pedal to take full control of pitch bending and unleash dive-bombs with precision.
Prepare yourself to experience the ultimate in pitch-shifting, octave generation, and analog fuzz!
