A ring modulator outputs the sum and difference of frequencies in multiple waveforms.

More information in Wikipedia.

Special Ring Modulator effects


The Ring Modulator works great as an octaver (adding a low octave).

Enable the TRACKING parameter, set FREQ at 500 Hz, and turn down HI CUT to 500 Hz or lower.


You can configure the Ring Modulator to act as a tremolo, by turning down Frequency all the way.

"Evil Whammy"

Attach a pedal to the FREQ parameter.
