MXR M288 Bass Octave Deluxe

The Bass Octave Deluxe offers two independent analog sub-octave voices with a Dry control and a Mid+ switch to optimize the sound of your parallel clean signal.

• This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).

The Bass Octave Deluxe is a dual-voice octave pedal that offers analog tone, true bypass, and a variety of tonal options. MXR's 18 volt Constant Headroom Technology™ provides high headroom and superior tracking. Use the Dry knob to mix in your direct signal, and hit the Mid+ switch to add up to +14dB of internally adjustable mid frequencies (400Hz or 850Hz). Finally, mix in two separately controlled octave voices—Growl (for throaty tone) and Girth (for deep tone).
