MXR M306 Poly Blue Octave Guitar Pedal:
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.
This pedal is powered by one 9-volt battery (remove bottom plate to install). Optional power(sold separately) is a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU, or an MXR Brick Series power supply.
