Barker ASSMASTER
Harmonic Octave Analog Distortion Pedal
The Malekko Barker ASSMASTER is inspired by the original Maestro Bass Brassmaster octave pedal. Hand-built by us, this modern version delivers the same octave overdrive/harmonic generation effect in a quiet, fully controllable pedal. It features a recessed LED indicator, a pop-free true bypass switch, and a tough lexan face. The 5 controls provide complete control over the tone, overtones, harmonics and mix of the dry and wet signal.
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 adaptor (neg tip) or internal battery snap.

The ass volume controls the volume of the distortion signal
The ass switch selects the tone of the distortion
The bass volume is the dry signal control; also provides massive gain to the dry signal
Harm selects the harmonic spectrum of the effect
Sensitivity controls the depth and response of the effect from subtle to excessively saturated
