## Overview

The MXR® Bass Octave Deluxe M288 is a premium analog octave pedal featuring 18V Constant Headroom Technology for superior tracking and clarity. It offers two independent octave voices with organic tone, a Mid+ switch for customizable midrange boost, and true bypass to maintain signal purity. Built in a durable metal chassis, this pedal is designed for professional bassists seeking versatile, high-fidelity octave effects that stand out live and in the studio.

## Description

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).

Review: A worthy EBS Octabass replacement - I have an EBS Octabass that I use extensively live but the pedal just wouldn't track low or sustain very well so after some research, I found a lot of positive reviews on the MXR M288 Bass Octave Deluxe. I A/B'd both before giving the MXR the seat on my board and have to say the pedal does everything it should be doing. It tracks fast, long and low while having a more "square wave" tone than the Octabass which was more of a "sine wave." This is especially noticeable when none of the bass's dry signal is added. You get this square Moogish, synthy sound that's very usable when coupled with an envelope filter, distortion and other fx. Build quality wise the MXR is decent but the EBS Octabass still wins and it is a good pedal, just not as good at tracking as the MXR.
Review: Great pedal - I used an OC-2 for many years. The mid boost finally convinced me to pull the trigger on this one. I tried this out at a gig, and I was more than happy. My coomplaint with the OC-2 is that it always seemed like there was a volume cut no matter how I set the pedal, this one has almost more Octave than I needed. I have had the EH Ocatve Multiplexer, the MXR octave, the Boss Super Octave, and this one gets closest to the tonal profile of the OC-2. It felt and responded like the OC-2, and I can’t say enough about the adjustable gain and mid boost. You could almost just use this as a mid boost pedal. It fits exactly a Boss pedal space, although the input jack is slightly lower than a Boss. The ac Jack is right next to the input jack which is a little wierd, but I guess they are trying to make all of the things sticking out of the box in one spot. I never thought I would retire my OC-2, but the time has finally come. The order I ran this was Bass, MXR, Slow Engine, Mid Boost pedal, tuner.
