Used MXR POLY BLUE OCTAVE Effect Pedal

Used but in excellent condition, the MXR Poly Blue Octave pedal is a reliable and versatile tool for guitarists seeking rich, immersive octave effects. With its blend of mono and polyphonic capabilities, it provides everything from classic analog-style octave-down warmth to modern, precise pitch tracking. Independent level controls for each octave voice (one and two octaves down, one and two up), along with built-in fuzz and modulation effects, give players the freedom to shape their sound with confidence. True bypass switching preserves your core tone when the pedal is disengaged, making it a trustworthy addition to any signal chain. Built into a durable, compact enclosure and powered by a 9V adapter (not included), this pedal is a performance-ready solution for musicians who value both tonal depth and dependable gear.
