Dual-voice Octave Pedal with Organic Analog Tone

The MXR M288 Bass Octave Deluxe Pedal, is a dual-voice octave pedal from MXR Bass Innovations that offers organic analog tone, true bypass, and a wide variety of tone-shaping options. Powered by a single 9-volt battery, MXR's 18-volt Constant Headroom Technology (CHT) provides studio-performance headroom and superior tracking. Use the Dry knob to mix your direct bass signal with the octave effect, or hit the Mid+ switch to add up to +14dB of internally adjustable low-mid punch (400Hz) or midrange pop (850Hz). Bass players will love the two separately processed and individually voiced octave controls - Growl (for throaty, midrange octave-below tone) and Girth (for deep and smooth octave below). The Bass Octave Deluxe comes in a durable, lightweight aluminum casting and has the same high-quality jacks and switches that have made MXR pedals the road-ready standard on pedal-boards around the world for over 30 years.

Constant Headroom Technology
The CHT circuit produces 18-volts of headroom from a single 9-volt battery or external power source. CHT utilizes voltage step-up techniques, which supplies constant 18-volt headroom regardless of source voltage. For example, CHT will produce 18-volt headroom from a used battery down to 4.5-volts and voltages up to 30-volts. CHT also protects against incorrect reverse polarity and AC voltages.
