Inspired by the Maestro Bass Brassmaster octave fuzz, the Malekko B:ASSMASTER delivers the same octave overdrive and distortion but in a totally quiet and controllable pedal. With an expression jack for control, three knobs, and two switches for tonal shaping, overtone shaping, harmonics, and dry/wet mix, the B:ASSMASTER brings on the fuzzy distortion for basses.
