Used Keeley Octa PSI Effect Pedal

Add massive octave textures and synthy grit with this used Keeley Octa PSI in great condition. Designed for guitar or bass, it blends octave-up and octave-down voices with fuzz-like drive to create everything from classic octave leads to thick, sub-heavy riffs. Simple top-mounted controls make dialing in the mix fast, while standard 1/4" in/out and 9V DC center-negative power keep it pedalboard-friendly. A bold, inspiring effect for players chasing bigger tones.
