The LastGasp Art Labs GOMORRAH (GMR) is a subharmonic fuzz pedal which creates a synthetic lower octave sound.
The pitch of octave sound depends on the intensity of the input (instrument) signal. The basic idea is that if the input signal is strong, the input pitch is output. The output pitch is one octave down if the intensity is middle, and it is two octave down if the intensity is weak. The pitch steps is caused by the input signal and it acts a random arpeggiator.
