Re: capacitor value
.022 uF and .047 uF are the most common stock caps. Usually, those are used for humbuckers and Fender single coils, respectively. I prefer starting at .01 uF and going down from there as needed, as I usually find both .047 and .022 too muddy when the pot is on 0. However, go to .01 or lower, and you get some great cocked wah sounds on 0.
