Used MXR Poly blue octave Effect Pedal

Used MXR Poly Blue Octave effects pedal in Fair condition, delivering glitch-free polyphonic octave tones for guitar and bass. Blend up to two octaves down and one octave up with independent level controls, then shape the sound with built-in fuzz, modulation, and a MONO/POLY switch for classic or modern tracking. Housed in a rugged compact stompbox with standard 1/4" input/output and 9V DC power (center-negative). Expect visible wear and honest playability.
