I couldn't hear any difference on this either! Turning both knobs did nothing."I got an idea, without desoldering anything, can I alligator a whole separate presence circuit for testing? Take alligator from the NFB resistor and have it go to a pot/cap arrangement and test what that does?"
You should also add a new cap to that new pot for testing in that manner.
That would give two possible outcomes, I think:
1 no difference which means the current pot is shorted to ground
2 big difference which would mean the current pot is open (given that currently nothing happens)
3 You can't hear any difference lol
Here's how I had it set up, using a .68uf cap. Just kind of did a mirror image of the existing one, utilizing the same 4k7 resistor that's in there and a new cap and pot. I used a 100k pot with 5k6 parallel to make it close to 5k.
