The Rockman Distortion Generator is an excellent and dynamic distortion. It has 3 band EQ, Phase Notcher, Auto Clean, Treble Boost, and different input and output levels. Every control to get the noise you need! You have to use a separate footswitch (you can easily make one of these!) to bypass the distortion. Runs off 120v AC (plugs directly into the wall - does not use batteries or adaptor)
