I have a Squier Strat SE and am installing new everything under the pick guard and I am going to do the following: Wire up so that 2nd tone knob works for both middle and bridge. Install a separate tone cap on each tone pot, these will be 2 different values 0.022 and 0.047 so that neck will give one sound and middle / bridge another. I will also be installing a treble bleed kit. My question is in regards to the tone caps, it's my understanding that different capacitors allow more high end to pass through. So if I want my neck pick-up to be darker than the middle/neck which cap goes to the neck circuit the 0.022 or the 0.047 Does larger value = Darker tone?

paully-
Hello and Welcome to G-Nutz2!
Sorry, I had to move your thread here, to guitar wiring.
Err, not quite. I moved your thread from JohnH's tone control discussions, which has a thorough exposition of this topic (hint: required reading).
First, the treble bleed kit goes on your volume control, to prevent loss of treble as you reduce the volume. We want the volume control to simply reduce output, not to alter the tone. But a normal volume control skews the frequencies bass-ward as it is turned down, and the treble bleed is designed to prevent that.
On the tone control(s), we want the treble to reduce- that's what a tone control is supposed to do.
Second, understand that with the tone control at "10", the cap is effectively out of the circuit, and has no effect on the tone. Assuming the pot is functioning as it should, the pickups should sound the same at "10" regardless of the cap values.
The cap alters the frequency response curve as the tone knob is turned down. Again, see JohnH's discussion for the details, but generally, a .047 is used with humbuckers precisely because they are darker-sounding, and the larger value cap keeps a bit more brightness as the knob is turned, making for a more useable tone control. That's a bit oversimplified, and I'm sure someone will be along to give you a more technically correct answer.

I'm afraid I have to disagree with newey. Cutoff frequency is inversely proportional to cap value. Bigger cap means lower cutoff which in an LPF like this means darker.

Ash is correct, my mistake. The main thing I wanted to dispel was the suggestion that this would affect the sound overall, when the control was not being used.
