I swapped the stock cap in fender jazz to a 0.01 uf and I have noticed some bizarre goings on. With the tone control full up, all is normal. With the tone half down, it sounds like the stock, but all the way down. With it all the way down, it has a mid-boost, and sounds great for getting a pickstyle growl out of it. How has this happened? I thought caps took treble away? Anyway, I'm keeping it like this because it sounds soooo cool.
