The MXR Poly Blue Octave brings modern and classic pitch-shifting styles together with fuzz and modulation to create the ultimate octave pedal for tonecrafters and sonic seekers.
The MXR® Poly Blue Octave is powered by a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU or an MXR BrickTM Series power supply. This pedal cannot be powered by a battery.
