The one thing im known for at the shop, is my treble bleed circuits, and that's because I make them custom for each guitar. The values for what works for each guitar can swing wildly. Start with all the recommended values, and buy some resisors, from 100K on up to 330k. Each guitar will be different in what it requires. Strats tend to need lower values, ifyou use one with a value too high, it will actually ADD treble as you roll down the volume as opposed to just mitigatig its lost. It will make it sound think.
Also, with the resistors; these are used strictly to adjust the taper of the pot. Sometimes a volume kit will make a normal acting pot, one that gradually goes up and down, and make it so; maybe from 1-5 you dont hear much of any change, then from 6-10, it goes right up, or vice versa. Not all gutiars will need the resistor.
But also, some that do require the resistor work best when its wired to the cap in parallel (one leg from one resistor is wrapped around one leg of the cap, and the other leg is wrapped around the other pot). Some work better in series (you solder one leg of the cap to one leg of the resistor, and thats it, so It will be one long component).
Go buy a handful of caps and resistors, open the pickguard, hook a pair of alligator clips to the lugs of the pot, let the 2 wires hang out, and scew the pickguard down, and tune to pitch. Now you can try all the different combinatinos without soldering, then removing and having to resolder.
You see a lot of "Volume Kits" on eBay that have one for humbuckers, and one for single coils, while this is better than one size fits all, it still isnt true. What works on one strat, may not on another, even with the same pickups. The pots have something to do with it, its hard to match two pots values identical.
This is the right way to do it, and the way to get the kit that will retain the treble without adversely having a bad affect to the taper of the volume pot.
The last one i did was for a guy who had an Am Deluxe completely overhauld; Lollar pickups, new pots, caps, series/parallel, etc. He had mhy friend sit with a pile of pots, and measure them to get the 2 that were" exactly the same value" this obvioulsy didnt work. But the pots they put in, had a real bad taper. The volume only really gradally rolled off from 10-6, after which it just dropped off completely. I told him it may make the taper worse. But i put together 4 different kits; 2 different values, then each value had one wired in series, and the other in parallel. Once i put the second one in series, i hit a chord and rolled down the volume,and everyones eyse widend. IT was perfect. As i rolled down the volume on the guitar, the guy rolled down the volume on the amp, and the tone remained the same. But what was really nice, was that it made the pot useable. The guy actually emailed me last week to thank me, and told me its the first guitar he's owned where he gets use out of it with the volume down to 23.
