Fairfield Curcuits make great sounding, simply designed pedals and the Randys Revenge is a stunning Ring Modulator. At its finest, in a considerably small package, powered by your typical 9V power supply, all analogue, 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.

The lower oscillator frequencies create rich trem/vibe effects, excruciatingly slow or chopped up rhythmic flavours. 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).

NOTES ON POWERING

Randy’s Revenge was designed to operate using your typical centre negative, regulated 9-9.6 VDC power supply. The pedal is protected against reversed polarity and overvoltage conditions. Always check your power supply for proper voltage and polarity before connecting. There is no battery connection inside the pedal.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

Filter

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Synth

A synth pedal transforms your guitar signal into rich, layered tones that mimic the sounds of a synthesiser. Using pitch tracking and waveform generation, it can produce everything from deep bass lines to shimmering pads and futuristic leads. Synth pedals open up a wide creative range, blending the expressiveness of guitar playing with electronic textures, making them ideal for experimental sounds, ambient music, or adding a modern edge to classic riffs.
