I want to check my math with the experts. If I have a guitar with all 500k pots and I want to change one to 250k. Can I install a 500k resistor parallel to the pot (from one pot end to the other) to change the value of the pot? I have a guitar with 500k pots that I want to try at 250k just for S&Gs, but I don't want to do a complete changeout since the current pots are push-pull with DPDT switches that I don't feel like rewiring.
It seems like it would work on paper, but I want to ask the experts since I'm not 100% confident. Thanks for the help.

It will work ... sort of.
By putting at 500k resistor between the outer lugs of a 500k (forward wired) volume pot, it will load the pickup the same as a 250k pot. But the taper of the pot will not be the same as a 250k pot. In general, this will give you a decent idea of how a 250k pot would affect the circuit. Also, the impedance at the output, will be higher with this modification, as the volume is turned down, as compared with a 250k pot.
This is a reasonable thing to try, even if the results aren't precisely the same as installing a 250k pot.
btw, I looked through your previous posts. You've been here a few times, for quite a while, but never got a proper welcome. so...
