Here's a later version, with changes made as per suggestions from PRR and bcarso:
One channel shown, of a matched-gain 4-channel version.
I tried an 072 as the first stage, and it seemed to want to oscillate rather too readily. Currently I have 5532's in there and it's not too noisy, though I have some investigating to do.
Anyone see anything easy ways to improve this? -The 39K resistors have been scaled to match each gang of the pot's static end-to-end resistance, for improved inter-channel tracking.
