I'm selling this because I no longer use it, though I used it on a board! There are no issues with its operation. Body only. The Angry Charlie is equipped with five controls: VOLUME, DRIVE, BASS, MIDS, and TREBLE. The VOLUME control functions like a normal master volume on an amplifier. Simply turn it clockwise to increase the volume and counterclockwise to decrease it. The DRIVE control controls the overall amount of distortion/overdrive and inputs into the signal path. Turning it clockwise increases the distortion, while turning it counterclockwise reduces the amount of distortion. What's new in V3 is the addition of the BASS, MIDS, and TREBLE controls.
