New and unused. I recently received this as a gift. The MXR POLY BLUE OCTAVE is an octave effect pedal that combines fuzz and modulation, offering flexible and powerful features. It allows for a wide range of sound creation when playing single notes or chords, and delivers diverse expressive power in live performances and studio recordings. The octave controls feature four independent level controls for 1 & 2 octaves down and 1 & 2 octaves up. Included accessories: Genuine power adapter, serial card, quick guide, box Please feel free to ask if you have any questions. No claims, no returns. Thank you for looking.
