MXR Octave / Pitch Shift Pedals

Explore MXR octave and pitch-shift effects at GarageBand Music, featuring the M306 Poly Blue Octave. This pedal combines modern and classic pitch-shifting styles with fuzz and modulation for experimenting with octave-based textures.

Review the Poly Blue Octave listing to explore its features and plan how it will fit your effects setup. It requires an external 9-volt power adapter, such as the listed Dunlop ECB003/ECB003EU, or a compatible MXR Brick Series power supply. The pedal cannot run on a battery. Check power-supply compatibility and included accessories before ordering.
