Anyone have a recommendation for the value capacitor used on a P90 loaded guitar?

I like a .022 or a little less. You can roll off some of the real highs if you need to without cutting into the meat of the P90. A .05 cuts into the upper mids too much for me.

Thanks for the response. I started looking around the LesPaul forum a bit. Looks like .02 was the cap used in the early releases. Not sure what they use now. I'll give it a try.

Try this.... simple and easy... I have a setup like this at the shop to help customers decide what they want.

My Asher has a 0.033 I believe.

Years ago, the tone pot for my rhythm pickup broke on my P90 Les Paul. My brother clipped the pot and cap out of the circuit until we could get parts and get it fixed. (This was well before the internet could land parts at your door within a week.)
When we finally rewired it and got the cap back in there, I missed the additional brightness of not having a cap in the circuit. That cap has been out of the circuit since somewhere around 1980 for me.

Don't forget the pot rating ie 250k or 500k and the way its wired will also make a difference.

If your finding it dark then putting in a smaller value cap might do the trick to brighten it up. I am assuming it's a Lester your talking about. You could also try 50,s wiring or a 550 k pot if brighter is what you are trying to achieve. I have a humbucker size P90 in a Tele neck position and its a bit of a compromise using a 250k pot to keep the bridge pickup where l want it so changed the 047 to an 033 and did the 50,s wiring and all is well but occasionally need to roll the tone off when on the bridge.

The guitar in question is a Grosh ElektraJet. Right now it has 500K ohm pots. It also has a RC treble bleed circuit. I want to switch things up a bit to see if I can get more usable tones with my current rig. She's a player and sounds great as is. I think she can sound even better with a little tweaking. I plan on switching to Gibson 50's style wiring. Maybe even switch out the volume pot for a 250K vs. the 500K presently in place. Also will try a R treble bleed circuit replacing the current RC treble bleed.

I'd remove the treble bleed altogether. Never heard anything good when I've had them on in the past. I imagine the Grosh came with tight tolerance pots like my 290 did. That allows for much more play on the dial with clean at 5 and mean at 10. With P90s a 500k ought to be bright enough. MarkT put some different caps in the 290 before i got it from him. Maybe he can elaborate.

I'm not a big fan of the RC treble bleed circuit. It's a really well made guitar so I have been hesitant in making any adjustments. I'm still hesitant. Fortunately this is not the original pickguard/pickup assembly. So I feel a little better about playing around with it. I would love to go with an upgraded trem block as well. That's a whole 'nother thread though.

I'm working from memory which might not be a good thing. I believe my Les Paul has 500k pots in there. I remember going through another experiment with my brother to try 250k or 1 meg pots. Whatever we tried really darkened the guitar which isn't my thing, so we went back with the original values.

I'll try changing the treble bleed circuit first to see what changes I get. And then I'll go from there.

MarkT put some different caps in the 290 before i got it from him. Maybe he can elaborate. For P-90's with 500K pots as in Chris's 290, I used Angela/Jensen Copper Paper in Oil .015 for the neck pickup and .022 for the bridge. I put the same set in my new CL. Sweet match up in my opinion. When you roll the tone all the way off, it's not as dark as with a .049.. That sweet woman tone.

Don't change to 250k pots!!! The higher the value...the brighter it will be. 250k will make it even DARKER.
I would go with 1M pots....if you want more brightness. And also raise the pickup. The closer the pickup is to the strings...the brighter it will be.
Also, check your cable length. If you have a total cable length of more than 20ft of cable (and all true bypass pedals....ie..no buffer).... the capacitance of the cable will attenuate the high frequencies.
Hope that helps....
BTW....there are things that you can't change.. like scale length. I actually just built a Warmoth Les paul...because I hate the 24.75" scale length. It's too dark. I needed a 25.5" scale.
good luck.
Jacques

I love you guys...
I don't even know what a capacitor is or what it does.
BUT:
If my stuff sounds bad (like my '65 ES330, although it never has since I got it '68), I take it to guys like y'all.
YEAH!
