RAPTIO is a glitch/hold effect pedal designed for extreme guitar playing. The toggle switch allows you to switch between Glitch and Hold modes. Glitch mode produces a tricky glitch delay sound, while Hold mode continues to extend the sound while mixing in a sound delayed by 1mSec to 10mSec. Wet Volume controls the volume of the effect sound, while Dry Volume controls the volume of the original sound. Rate Control changes the repeat speed in Glitch mode, and changes the mixed delay speed in Hold mode. A momentary footswitch that turns the effect on only while it is pressed. In both Glitch and Hold modes, the sound will not decay forever while the footswitch is pressed.
