“WORMHOLE” is a delay pedal that can bend delay time by the reflective photosensor. When the repeat knob is full, it starts to oscillate. Because it has a limiter circuit in the feedback section, it doesn’t make too much of a loud oscillating sound. You can get a kind of vibrato or chorus sound when the time knob is in a lower position.
