makes a soemahwat tuneable feedback noise at any amplifier settings... its also a generic 80s distortion effect not unlike a DS2. I suspect its a DS2 circuit with a cocked wah thing built in. thatw as all ther age for awhile when Iw as a kid. really goofy effect. Best sued when you have to fil in for Snowy White in Roger Waters band or when you just want to annoy people.
Strike a chord and listen to the massive feedback wave fill your guitar amps cabinet! very cool for feedback effects! And Its a very aggressive Distortion!
