Treble Bleed Cap and Resistor Values?

Hi All,
I have a couple Strats in which I have a Duncan JB (full size) in the bridge, Duncan Classic Hot Stack in the middle and a Vintage Hot Stack in the neck. I have one of the tone pots as a push/push for splitting the coil of the JB for some stuff. JB is wired to one tone pot, neck and middle to the other. All three pots are 250k pots.

I'd like to install a treble bleed mod but am not sure what value cap and resistor to try. I'd have to order the parts so I kinda wanna avoid ordering a bunch of stuff that'll end up going unused. I was hoping some pickup gurus here could help me in the right direction for these particular pickups.

If this post is a duplicate of an already existing post, or if I'm posting in the wrong place I apologize. Thank you in advance for your help!

All you need is a 100-400pf cap. 100 range is a subtle difference. 2-300 range is about the same brightness with the volume rolled back as with the volume on 10. 400 and up is brighter as you turn the volume down. You can score a cap set for cheap on ebay.

So you're saying I don't need to add a resistor in there? How some some people prefer using a cap and resistor? Just wondering as I'm electronically ignorant...

I am zero help on the treble bleed as I have never liked them. However, I did finally wire one of my HSS guitars using Suhr’s diagram and that make a pretty nice improvement.

If you are not familiar with, Suhr has a diagram that effectively has the humbucker seeingn500k and the singles seeing 250k. You can incorporate a treble bleed into it (Suhr does), but I was okay without it

Right. I've tried both and a cap only works perfectly fine. They sound similar and I think I prefer the sound of the cap only too.

What the resistor and cap does is you use a big cap which adds a lot of brightness but then a resistor counteracts the brightness and darkens the sound a bit... It's simpler to just use a small value cap.

Makes a lot of sense. Thank you.
I've tried a treble bleed a few times in the past and haven't really dug them much - always ended up cutting them out as soon as I could. My wonder is if I simply had too strong a bleed (too high a cap value maybe?) in there. I'd really like to have the treble to bass ratio stay the same as I roll the volume back. I've never had that...
