Analog Bass Octaver with two octave voicings and mid boost

The MXR M288 Bass Octave Deluxe is an extremely versatile bass octave with a juicy analog sound. Thanks to two sub-octaves with different voicings, the effect pedal delivers multi-faceted Bass sounds for almost any application. The Constant Headroom Technology guarantees a clean Tracking even on the low strings and a noise-free performance.

Growl and Girth

At the heart of MXR's Bass Octave Deluxe are two independent sub-octaves with different voicing. The Growl named octave stands for a throaty sound with emphasis on the mids. Girth, on the other hand, has a smooth and deep sound character. Thanks to the controls for Growl, Girth and Dry, both sub-octaves and the clean signal can be mixed in any ratio.


In addition, the M288 Bass Octave Deluxe from MXR has a mid-boost ready, which gives the sound more bite and assertiveness if desired. In addition to switchable center frequencies at 400 Hz or 850 Hz, the level of the boost can be adjusted between +4 dB and + 14 dB.
