This is a very rare ring modulator pedal in Excellent Condition. Power Supply not included.
This pedal allows you to ring modulate either to an internal oscillator or to a second audio source. You can ring modulate a guitar and a drum machine, radio noise, or any other sound source. Additionally, there is a control voltage in to control the internal oscillator. It can be used to hook up to a footpedal to control the pitch of the oscillator.
Description from the web: Ring Modulator w/ external CV input Get those wild Sci-fi robot sounds. The ring modulator uses an internal oscillator and balanced mixer to generate new harmonics that correspond to the sum and differences of the frequencies of the input signal and the local oscillator. For example if the input signal from a guitar or keyboard is 800 cps and the local oscillator is at 600 cps then the output will be two frequencies of 200 and 1400 cps. The level of the output signal tracks the level of the input, so the original signal is transformed into new frequencies.
