Master: Controls the volume of the circuit of the corresponding side - left MASTER controls the left side volume and right MASTER controls the right.
Drive: Sets the amount of drive for the corresponding circuit.
NOTE: Channel 1 is activated with the right side footswitch and adjacent controls, always remaining the Interstellar Overdriver circuit. Channel 2 on the left, however, can be altered with the rotary to become something completely new. Both sets of controls will interact with one another to produce new, insane tones depending on which rotary position is selected - everything from piercing overdrive, to oscillations, and choppy trem.
