Keeping it simple without all the technical details, the Gristleizer in its essence is a low frequency oscillator with different waveshape options that interacts with a tremolo (VCA) or Bandpass Filter (VCF). There is a lot of versatility in this circuit which can get all kinds of tones, tremolo, auto-wah, pseudo ring modulator and all kinds of quirky in between 'broken' sounding modulation. 

Controls;

Bias - LFO voltage Bias for making the LFO oscillate properly, can be adjusted to taste but typically is set for the strongest sounding oscillation

Depth - sets the amount of oscillator you want to blend into the dry signal

Gain - Determine how much overdrive you want in the circuit, an added feature that the original designer Roy Gwinn gave me some tips on. A little goes a long way as you can hear in the demo.

Level - sets the output volume

Speed - how fast or slow the oscillator wave moves

Waveshape -Square Wave, Triangle, ramp up sawtooth, ramp down sawtooth

VCA - Voltage Controlled Amplifier (Tremolo)

VCF - Voltage Controlled Filter (Bandpass Filter)

This pedal also doubles as a signal buffer. A Klon style buffered bypass was added to squash the oscillation feedback that happens with true bypass high gain pedals and also adds signal integrity to a signal chain. 

 *Note* This pedal runs on a standard 9 Volt centre negative power supply which is not provided, for suggestions on power supplies see the info section.
