treble isn't working at all. The rest of the tone stack seems ok. I replaced cap in c19 and tested the treble pot . Pot is good. no change with a cap in c19 or without a cap in c19. Anything else i should check in the tone stack? I'm guessing c19 is a coupling cap. Is there other parts concerning the treble that i should check first? Could a bad resistor cause this to happen? I just think that if there was a fault with any of these parts i wouldn't get sound at all. Thanks for any suggestions
