R203 is the Trebel Control and R207 is the Base Control.

Unfortunately I don't have any thoughts on what could be wrong. If it were me, and it has been, I would double check the wiring ... I've driven myself crazy by mis-wiring something.

Bob,
So you can agree that if the pot checks out with the ohm meter, then the problem is elsewhere? Also, I can't help but think that there's a clue in that both the bass and treble pots are dead. Too much coincidence.
Thanks,
Alan
