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).
Power: Dunlop ECB003 AC Adapter or Single 9 volt battery
Great Octave PedalBy: Tim Seeley on 22 April 2017Two distinct voicings with three volume controls: one for each octave-down voice and the third for your dry signal. Can be applied gently to fill out your sound with a bit of subtlety, or strongly for a full-bodied synthy bass sound. Tracks quickly and precisely within working range. Starts breaking up as you get down close to low E, so on 5-string bass don't expect this pedal to give you an octave below your low B string. Sound also tends to break up semi-randomly if you play multiple notes at once ... which can actually give a nice effect in some situations. For some songs, I prefer the sound of playing an octave higher on my fretboard and using this pedal to drop the pitch back down. Also works great with a bit of fuzz on the input side, and an MXR Bass Envelope Filter pedal is a great downstream addition - but of course it depends on the song (sometime less is more). The nice thick voice instantly turns some boring-bassline songs into solid rockin' goodness. The mid-boost option is also great, and gives you the option of some extra cut-through for spots in a song where you want to stand out a bit. The mid-boost switch needs a finger press, unfortunately - your foot's not going to get to it. If you're a bass player starting to wonder about getting into pedals, I'd recommend the MXR Bass Octave Deluxe as a GREAT STARTING POINT. Of all my pedals, THIS IS THE ONE I USE THE MOST.
