Hello uwood.
Correct,
U1 is a buffer, U2 is a inverting configuration with 10x gain. U3 has a non-inverting gain of 21 that can blend between the high filtered and the low filtered signal.
RV1 works as a voltage divider/attenuator for the incoming signal.
Surely you will half the maximum gain if you replace the 1M with a 500k but here a question:
"The input gain control with the pot does not work for one of my audio sources" means that the pot is damaged?
In that why not replacing the potentiometer instead?
Or maybe i missed something
