Used MXR POLY BLUE OCTAVE Effect Pedal

Used and in great condition, this MXR Poly Blue Octave pedal delivers rich, layered octave effects that are perfect for experimental tones and dynamic soundscapes. Combining mono and polyphonic capabilities, it offers both classic analog-style octave-down tones and modern polyphonic tracking for precise pitch shifting. Featuring independent level controls for each octave voice (one octave down, two octaves down, one up, and two up), plus a built-in fuzz circuit and modulation effects, it offers deep tonal flexibility. True bypass switching ensures your original tone stays untouched when the effect is off. Powered via 9V adapter (not included), this compact and rugged stompbox is ideal for stage and studio use, offering expressive control in a pedalboard-friendly enclosure.
