Used Keely OCTA PSI Effect Pedal

Used Keeley Octa PSI in good condition, delivering thick octave fuzz and synth-like textures with classic Keeley build quality. Featuring straightforward controls for tone and output plus independent octave and fuzz voicing, it’s easy to dial in everything from gritty lead boosts to massive, glitchy octave walls. Standard 1/4" input/output and 9V DC center-negative power provide easy pedalboard integration, while true-bypass switching keeps your core tone intact when disengaged.
