After getting it home I found that it had some static issues and the treble pot was not working in the PTB system. I opened her up and found what appear to be all original, untampered-with electronics and those sweet Duncan SSL-2s. To my surprise neither the volume or treble pot were grounded, and since the output jack was "grounded" to the volume pot then the output jack wasn't grounded, either. My multimeter confirmed that only the bass pot was grounded. Weird! There we no extra solder joints, no evidence that there was ever a ground wire between the pots. I have to assume it left the factory that way given how clean everything was. Check out the photos.
I soldered a ground wire and now everything works and sounds great. This seems like a pretty big miss from the factory back then. But, then again, the body is stamped Dec 18, 1992 -- the Friday before Christmas week.
Thought I'd share the story. Enjoy!
