So I figured we have this new area and might as well add a thread that I'm pretty passionate about: Treble Bleeds.
A Treble Bleed is a nickname for placing a small value capacitor across the lugs of a volume or tone pot, or both, in one of several combinations, so that the high end is retained when you roll off the volume knob.
Each guitar is different, and I've used a slightly different one on each of mine. I do lots of fidgeting with my volume knobs on all my guitars while playing. Almost as bad as SRV, really! I also do LOTS of Keaggy-type volume swells. For this, you MUST have a good treble bleed or it just sounds like mud.
I recommend ceramic caps whenever possible on guitars, then poly film (greenies) after that. I've tried metal film and it just doesn't sound good, almost like turning a switch on and off because they're so tight and clean.
So what's your favorites? Here's mine:
Les Paul: I like the .022 from ground to the Tone wiper, and a .001 on the Volume pot input to the wiper. (<- wiper means center lug of a pot.)

All 500k pots.
Yamaha RGX A2 (looks like an iPod) : I like to use a .0022 w/ 200K - 220K
in parallel across the Volume pot input to the wiper. That rolls off everything very evenly and smoothly, full range. An excellent mod for Strat style guitars that use humbuckers! Also 500k pot, no tone control. You can also try other parallel combos: .003 w/ 220k , .0022 w/200k, .001 with 100k or 150k...
Tele: Easy. Typical .047 from Tone wiper to ground, and
maybe a .001 from Volume pot input to the wiper. The latter part depends on if the volume pot is 500k or 250k. I think mine is 250k with just the Tone pot cap.
Strats: Gotta admit, I've never found a combo there that I'm really happy with, especially if there's a humbucker in the bridge. But usually I just stick a .047 cap on both the tone knob and the volume knob. I think. It's been a while. Kinda gave up on strats a while back...
