Keeley Electronics launched the Octa Psi Transfigurating Fuzz on September 24, 2024, a pedal that combines an all-analog fuzz with an octave generator and pitch-shifter¹². MusicRadar reported that Robert Keeley and his team spent over three years making it¹, and Guitar World published a statement from Keeley saying his whole team had been working on it for three years³.

The fuzz circuit is all-analog and transistor-driven¹, with Fuzz, Level and Tone knobs and a three-way tone switch offering Punch, Psi and Scoop EQ profiles¹. Guitar Pedal X described the fuzz as leaning "very much into the Muff side of things" and listed a Low End EQ control alongside the three modes⁴. On the pitch side, a Pitch dial spans two octaves up or down with "nearly every harmonic interval" in between¹, and a three-way toggle selects octave up, octave down or dual modes¹. Guitar Pedal X listed the available intervals as detune, M2, M3, P4, P5, M6, octave and two octaves⁴.

There are footswitches for octave/pitch and fuzz; holding both down toggles the order of the two effects¹. Double-tapping the Blend knob switches the output between all wet and wet/dry blend¹. The octave/pitch side can run in momentary or latching mode, with an adjustable ramp speed for expression-pedal-like sounds¹. Guitar Pedal X reported that holding the fuzz footswitch flips between latching and momentary ramping modes, and that holding it at power-up switches between true and buffered bypass⁴. According to Guitar Pedal X, the rear ports are input, 9-18V DC at 150mA, remote (tip fuzz, ring octave), control (TRS expression pedal or TS order switch) and output⁴. MusicRadar reported that the jacks are top-mounted on an aluminum enclosure and the pedal was designed and built in the USA¹.

MusicRadar reported an introductory price of $249 direct from Keeley Electronics¹, and Guitar World reported the pedal available now for $249³. Guitar Pedal X gave a MAP RRP of $249⁴. Gearnews gave an MSRP of USD 279².
