Vintage Bass Octave

M280

The MXR Vintage Bass Octave upgrades the warm
analog sub-bass vibes of a classic circuit with superior
tracking, cleaner headroom, and the versatility that
modern players demand. This pedal delivers an
impressive range of smooth, musical sounds—from a
tone-thickening growl to chest-rumbling dub tones—all
in the lightweight, space-saving MXR mini housing.
