CLEAN MIX
The CLEAN MIX knob controls the amount of dry, unaffected signal
going to the output. The clean signal used in this control does NOT have
any TONE control applied. This control is especially useful for get-
ting back some of the low end frequencies that can be lost in the pure
distorted signal.
