I have wired many many guitars and am competent at soldering.
But this one has me stumped:
A late 70s SG that I rewired/upgraded almost a year ago has developed a weird problem all of a sudden.
As always, I used the 50's diagram posted here on the forum.
All of a sudden, neither volume pot will take the guitar to total silence.
With either (or both) pots on zero, a considerable amount of sound still there. Like volume on 2-3.
Doesn't matter which switch position. Works as it should except for that.
After a visual inspection that turned up nothing obvious, I gutted it and checked all the components, all OK.
Vintage taper CTS pots ranging from 484K (bridge vol) to 521K (neck vol) and vintage wind Fralins. NOS PIO Russian caps.
I didn't meter the caps, but the tone controls work nomally. With tones out of circuit the problem remains.
Gutted and rewired twice today, same issue. Has anyone seen this?
Next I think I'll try wiring it junior style (one pickup, no switch, etc) to try and isolate it.
What am I overlooking? This started up all of a sudden after working perfectly for nearly a year.
Thanks!
