MXR M288 Bass Octave Deluxe *Free Shipping in the USA*

In the words of MXR:

The M288 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).
