No, don't run it to ground. You don't want to short things. Just run the
wiper out so that it forms a series circuit with the amplifier input.
Essentially, you're just treating it as a variable series resistor.

I'll try the pot.

How do I wire it? Like this:

Or do I want the wiper to sweep to ground?

200K is way too high. The impedance will be too high to overcome cable
capacitance and electric noise. 1K would be more like it.

No, 1kohm would be worthless. It would provide somewhere on the order of
0.2dB attenuation, which would be inaudible.

I suggested 200k ohm as a POT value, so that he has sufficient range to
make
the determination. I suspect the resistance value that will provide the
results he's after won't exceed ~50kohm.
