The JHS Angry Charlie V3 has five controls: Volume, Drive, Bass, Mids and Treble. The Volume control acts as a standard master volume control on an amplifier. Simply turn the control to the right and you are louder, turn it to the left and you are quieter. The Drive control decides the amount of overall dirt/overdrive that enters the signal path. Turn it up for more distortion and down for less. New to the V3 are the Bass, Mids, and Treble controls. To faithfully replicate a Marshall amplifier we felt it was time to incorporate a full Marshall-style tone stack. All three of these controls act as a cut and boost, while at noon they are relatively flat. The right 1/4" jack is the input, and the left is the output.
