1 blisspop 5 months ago hi everybody, i'm about to install a tone selector switch into my guitar that has dynasonic pickups. when the tone selector switch is on bypass, i want to hear the brightness of the my 500k volume pot. but when the tone selector is put into it's 1st frequency roll off position, i want it to sound like i have have a 250k volume pot installed. does anyone know which value capacitor i should buy to accomplish this? i'm thinking either .01 or .0068, but can't decide. does anyone have any opinions? or, mathematical formulas to help me figure this out? any feedback would be much appreciated. thanks!
