Tone Capacitors. What's the Difference?!

[Rocinante_x1]

What is the difference in the .1mfd, .047 mfd, .033 mfd, and so on? I'm buying an all new wiring harness, and i need to know what the difference is between these capacitors so i know which one to get.
Any help appreciated.
Thanks!

The larger values will cut the treble more. Stock on a J is 0.047mfd. I believe this is stock on modern day Ps. I believe Ps from the 50s had 0.1mfd standard.
