Like this? Seems to work reasonably well. I do need to lower R24 from 10k to 3.3k to get roughly the same amount of gain but it's not a big issue. Should work okay.
I do have some distortion for frequencies under 1kHz. I don't know where it starts exactly but probably somewhere between 200-500Hz and gets worse the lower you go. Not something caused by the pot though. I think it's a circuit design issue.
