HARMONIC OCTAVE ANALOG DISTORTION PEDAL
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.
These merchants probably sell this module. Huh?
