Ring Modulation at its finest, in a considerably small package, powered by your typical 9V power supply, all analog, hand stamped, pure sine wave oscillator, low-pass filtered with a touch of class and apparently musical. These are the requirements of warp speed space travel; a regular occurrence when dealing with Randy's hardware.

Ring Modulation is the result of the multiplying of two signals, where one is typically a sine wave or another simple waveform. The sounds born out of it are in most cases atonal and drastically different from the source. Randy’s Revenge takes this concept much further and implements not one but two simple waveforms – square and sine. Also, the oscillator can be used in two frequency ranges – hi and lo. Another interesting addition is the 12dB/Octave filter that comes after the signals have been multiplied and only affects the wet signal. There is a Mix knob that allows you to dial in just the right balance of wet versus dry. All of these elements combined make for one beautifully articulated ring mod pedal.

The lower oscillator frequencies create rich trem/vibe effects, excruciatingly slow or chopped up rhythmic flavors. As the frequency goes up, thick bells, tuned intervals, low-fidelity synth-like effects are only the beginning. Experimenting with the low-pass filter cutoff frequency and the dry/wet mix will yield tones as strange or subtle as desired.

Featuring expanded control voltage (CV) capabilities that allow for interactions beyond the simple stacking of effects, Randy can be used to control and be controlled by other CV-capable devices. The stereo CV is switch-programmable for use with an expression pedal or as a 2-channel CV port. Both the oscillator and low-pass filter frequency are voltage-controllable. The internal oscillator is also available as an output, turning Randy into a stand-alone voltage-controlled oscillator (VCO).
