I hope you don't mind me just posting a link to a thread at another forum, but I figured I'd rather post the link to the thread rather than just "steal" the info and post it as my own. 
I was looking for info on treble bleed capacitor values and came across this thread at The Gear Page:
www.thegearpage.net/board...eble+bleed
If you scroll down a bit, there's a great post by Clorenzo in which he not only talks about the effect different values have on the frequencies as they roll down, but he also links to a great application. It's basically an MS Excel spreadsheet that charts the frequency graph for different capacitor and resistor values that you enter as you roll the volume control down.
By using this chart you can find which values should work best for you. (In theory, anyway.)
I've stopped off at a couple of different Radio Shacks looking for different cap values (680pf and 180pf in particular), with no luck. Using this program, I was able to find some values that keep the frequency curve VERY similar as you roll the volume down.
I was planning on using a 220k/680pf in parallel, but couldn't find the 680pf cap. What I ended up using, which yields a very similar curve was a 270k/470pf. This keeps the balance about the same as you roll the volume down.
Bookmark this thread and download that spreadsheet! (Make sure you activate the tool packs mentioned in the thread for the spreadsheet to work properly.
Just for reference, here's the graph of the curve of the values I used. It stays pretty close, and it sounds the way it looks.
