Trying to replace the worn-out Panasonic vol. pot, some of the traces lifted off and now I'm stuck with a "broken" SM IV.
I did snap some pix before/after the desoldering job, but I can't make out much detail from the photos (see below). I may post some more later.
I can probably reverse-engineer the damage given enough time, but right now I need a quick solution. (Symptoms: Getting low-volume fuzzy sound in right-channel only in non-crossfeed mode; crossfeed-mode adds signal to left-channel, but signal is not true left/right stereo, of course)
If anyone has photos or, better yet, a schema or board layout (Eagle) of the SM, or any other advice, I'd be grateful!
Thx!!

AFTER (magenta "trace" shows some of what tore out; I'm sure there's more damage because just a re-trace based on the magenta does not solve problem):
