For some reason I can't come up with a simple master gain control for a two channel audio amplifier. I want to use one potentiometer to adjust the gain on both channels at the same time (Master Volume). I would prefer an op-amp based design for this. PLEASE HELP!

Usually all you need is a dual gang POT like the audio taper version of PTV 112 or equiv. Why can't you use that?
