The Synthmonger Pulsemonger is unique guitar effect that takes an input signal, squares it up, divides it by 2 (the sub-octave), and sends each pitch through individual pulse width modulator circuits, generating synth-like tones.
Both pulse octaves pulsewidth/duty cycle are variable from about 5% to 50%.
There is an on-board variable shape triangular LFO that can modulate both pulses simultaneously. Chorus/vibrato/tremelo/synth fuzz and other crazy noises can be had with this pedal.
Open to trade for guitar gear of similar or greater value.
