The Fairfield Circuitry Randy's Revenge is an analogue ring modulator that allows you to create tremolo and vibe-like sounds as well as wacky science fiction or crushed effects. The central Frequency control determines the frequency of the internal oscillator, the SQ/SI switch determines the waveform and the "Lo/Hi" switch selects the frequency range processed by the effect. The low pass filter determines the treble content of the processed signal.
