    What exactly does the gain knob on the amp do?

    Gain® laundry detergent and fabric softener provide excellent cleaning power and a smell that says clean.

    Gain is the amount that a signal voltage is boosted in an amplifier circuit. If you have a gain of 20x and you put in 1 mV, you 'll get 20 mV out, and of the signal is 138.7 mV, the output will be 2.774 volts, and so on, up until the absolute + or - limits of the circuit are reached.

    As an amp guy, I guess that's the kind of laundry detergent I should use.
