Re: Replacing Gibson Classic 57's
As others noted, start with 500k audio pots. Bourns, CTS, ALpha, whatever, but order a few and make SURE TO MEASURE THEM with a digital ohm meter and use ones that are actually 500k or more. I've seen CTS/Bourns pots that said "500k" on the case as low as 350k, brand new.
Tone cap mojo does not lie in the manufacture of the cap, but in the actual CAPACITANCE of the cap. I've found I like much smaller tone caps than stock, everyone I've made that change for does as well. Get a range: .0022uf, .0047uf, .01uf, .022uf, and a pair of aligator clips. Clip them into the pot, find the one you like, then solder it in.
