Experimental noise making at its best. Literally has an unlimited amount of sounds because it sounds different depending on the pedals that run in its effects loop. Plug your guitar in the input and your amp into the output while running anything you want in the send and return.
Has a volume knob to control the overall volume of the unit when it is on as well as a feedback control for dialing in a perfect amount of texture and tone. The toggle switch allows this to be used as a straight up True Bypass loop or a feedback/noise unit.
Single handedly the most creative and unique tool that an experimentalist can have in their arsenal.
