This is a passive ring modulator, which means it does not require any power source. It does require 2 input sources which can be any electronic instrument or mic. Sounds range from metallic to distorted and sci-fi sounds. This is awesome if used with a keyboard/synth and guitar or vocals. Some people have reported that you can use it as an fuzz/octave effect too. The onboard photocell (the red lens) reacts to light and shadow to manipulate frequencies along with the 2 control knobs.
