I know a guitar tech in my area who has a quart size mason jar plumb full of old used bumblebee caps. I had him install a .047 in both my electrics, one with Lollar Tele Specials, & the other has 2 Z90's. They were measured right at .047, I know cuz I measured them myself. These caps are amazing! They have so many tones available. I mean, the entire range of tone pot adjustment is highly usable, & they even do the Roy Buchanon, wah in the guitar thing. Most of the heavy treble cut happens towards full CCW, which allows for all the usable tones in between, & as a side benefit, they also allow for the highs to remain intact when turning down the guitar volume. Finally, real tone controls that actually work, & work wonders too!
