The M288 Bass Octave Deluxe from MXR is a dual-voice octave pedal for electric bass guitar. The pedal utilizes "Constant headroom Technology" to provide high headroom and accurate tracking. The Dry knob mixes in your direct signal, while the Mid+ switch adds up to +14 dB of internally adjustable mid frequencies (400 or 850 Hz). There are control knobs for dialing in the perfect blend of the two voices, which include Growl for a throaty tone, and Girth for a deep tone. The Bass Octave Deluxe offers true bypass and can be powered by a single 9V battery or a 9 VDC AC adapter such as the Dunlop ECB003/ECB003E, or a DC Brick power supply (sold separately).
Two independent analog sub-octave voices
Mid+ switch boosts selectable midrange
