MXR M306 Poly Blue Octave
Far more than just a simple octaver, the Poly Blue features four separate and adjustable octaves: -1, -2, +1, +2. Polyphonic by default, these octaves sound great for both single notes and chords. However, if you're looking for a raw, vintage sound, the monophonic mode offers the lower octaves the warm, analog sound of the classic MXR Vintage Bass Octave. The upper octaves, meanwhile, have the distinctive vintage sound of the Octavio Fuzz. Explore new sonic horizons with the MXR Poly Blue!
