Re: I want to ad switches to "standard Jem" wiring
The kill switch should indeed cross the live to ground when it's engaged - that'll close the circuit and eliminate that noise completely.
As for the 250k vs. 500k - yes, using 250k for volume will definitely bring down the treble content noticably, but that will remain a relative factor when you flick the switch to disconnect the tone control from the circuit.
If you're finding the 500k bright, then try out a 250k for the volume control. When you disconnect the tone control with the switch, you'll get back some of that treble content in the signal... might be more to your liking.
