Harmonic Octave Analog Distortion Pedal

The Barker ASSMASTER is proudly hand built by us in-house in Portland, Oregon using the highest quality components!

The Malekko Barker ASSMASTER is inspired by the original Maestro Bass Brassmaster octave fuzz pedal. Hand-built by us, this modern version delivers the same octave overdrive/harmonic generation effect in a quiet, fully controllable pedal. The 5 controls provide complete control over the tone, overtones, harmonics and mix of the dry and wet signal. True bypass.


We now offer an expression jack for the sensitivity control. Very cool! Get an expression pedal for hands-free sensitivity freakouts!


The pedal is powered by a 9v DC adapter (neg tip) or internal battery snap. Current draw is 50mA.
