Used MXR Poly Blue Octave Effect Pedal

Used MXR Poly Blue Octave in great condition, delivering rich polyphonic octave tones for guitar and bass.

Simple top-mounted controls make dialing in blends fast, while true bypass switching keeps your core tone intact when off. Compact, road-ready MXR enclosure with standard 9V DC center-negative power and mono 1/4" in/out.
