Featuring a dual-voiced layout, 14dB mid frequency boost switch and Constant Headroom Technology to ensure a stable effect presence, the MXR Bass Octave Deluxe proffers depths of low-frequency rumble. Using the dry knob to alternate or separate the two unique voices of aggressive or deep octaves, this effect can transport your sound right into the belly of stoner rock perfection.

  • I am going MXR for life!

    This octave is great! I play 5 string bass and the tracking is pretty good down to the low e if you are careful, even b can work but that's so few Hertz that it's tough to really hear. There's even great tonal shift to the sound of the octave you can achieve with some of the knobs. You will enjoy this octave pedal!

  • Sick sound

    Has a really rich thick sound and the mid boost adds definition. Gets a little muddy closer to the low E but otherwise excellent.

    Love this pedal and the service from the shop DISCO. The Growl/Girth settings are really brining what I hoped for. I haven't tried it life yet but I expect the mid boost to make the bass stand out in the mix.
