The M288 Bass Octave Deluxe Effects 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.
Since the early 1970s
Bass players world-wide have relied on MXR pedals to overdrive, funkify, EQ and compress their bass sound. MXR's commitment to bass players has been solidified by the development of the MXR Bass Innovations division”devoted to developing cutting-edge tools of creation for bassists on stage and in the studio. MXR Bass Innovations products can be found on such diverse artists' pedalboards as Robert Trujillo (Metallica), Leland Sklar (L.A. Studio Veteran), Juan Alderete (Mars Volta), Michael Rhodes (Nashville Studio Ace), and Marcus Miller.
