BASS OCTAVE M88

OCTAVER

The MXR M88 Bass Octave pedal is a bass guitar effects pedal designed to add an octave below the fundamental note to the player’s sound. It is powered by a single 9-volt battery or Dunlop’s ECB-003 AC adapter. The pedal features a dry/wet mix control, allowing the user to adjust the amount of octave effect in their signal. According to reviews, the MXR M88 tracks well with the player’s playing and continues to produce useful sub-tones for lower fundamentals, even when other pedals may give up.
