Depends on the pickups. With overwound pickups, I usually use Orange Drop 715P-200v caps in .010mf or .015mf. With '60's type winds or vintage winds I usually use .022mf or .033mf. These are the values that I've found to work best for me. You could go to .047mf or as high as .10mf if that's what you like.Originally Posted by ray82609
The older Strats from the '50's used .10mf and .047mf (or .050mf) caps. Later on they went to the .022mf's.
So, try lower value caps for the darker pickups, and higher value caps for brighter pickups. The only one who can tell you what sounds best to you, is you...so experiment a little. I find that having the right k-ohm value pot is an equal part of the cap/pot equation as well. I'll even try 300k pots with some Strats to get the right tonal balance. They, like the 250k pots have the +/- 10% variance as well, so I'll often use pots that are running in the 265k-285k range.
Of course, this is but a part of the overall equation. There's body wood, bridge materials (especially the inertia block), the nut, action height...etc. Guitars are like a big puzzle and putting them together is half the fun (for me anyway)
