This powerful and versatile ring modulator transforms anything you play into a whole new world of musical possibilities. By multiplying two signals, and outputting the sum and difference of all frequencies involved, you create exotic sounds previously unimagined.

You control the all-analog, pure sine wave oscillator with the Hi/Lo toggle and the Frequency control to create lush tremolo/vibe effects, rich bell tones, tuned intervals and vintage synthesizer sounds, then adjust the low pass filter and the wet/dry mix to fine tune it all as intense or as subliminal as you like.

A Control Voltage jack gives you and your expression pedal direct control over both the oscillator and low-pass filter’s frequencies. Six easily-accessed, programmable micro-switches inside the back of the pedal make it simple to control even more, with two-at-a-time stacking allowing for unique and fascinating interactions between parameters.

Because the internal oscillator is also available as an output, this pedal can be used as a stand-alone voltage-controlled oscillator (VCO). And all of this comes with a remarkably small footprint, and a remarkably small current draw, easily powered by your 9V power supply.
