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.

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).

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).
