    I'm sure there has been recommendations on this (maybe fairly recently) but I am hoping someone will give me a recommendation for the value of the pots and capacitors to use with P90's - and why.

    250k pots and .o22 cap for darker tone.
    Les Paul jr. Good tone is the reason

    300k pots/.022 for '50s Gibson authenticity. That may be too warm dark and woolly.
    Experiment with 500k pots and try a .015 and .010 cap for a more modern flavour. Particularly the neck pickup likes 500/015

    I'm planning to use A500K for Master Volume and A500K for Master Tone plus 22nF cap on my next project using P-90 pickups, and maybe a 120K + 1.2nF for treble bleed.

    A+!

    I’m a 500k guy for p90s. Anything frankly that isn’t a straight up single coil(I know p90s are, but they are rounder/fatter/warmer)gets 500k’s from me.

    I like bright present guitar tones. I find it easier to to dial back top end than it is to create it if it ain’t there.

    You P-90 fans (and I'm one of them) owe yourself a favor to have a listen to TV Jones T-90s sometime. I did and haven't looked back.

    TV makes great pickups indeed, my junior dc copy i sold had a duncan antiquity and that was very good, my stock '99 casino roars like a dinosaur and is one of the best tones i get. If they crud out i'd get T90's in there.

    The SD Antiquity line is one of my favorites. Sweet sounding pickups.

    yeah the kid who bought that guitar was really thrilled, like i was mean joe green throwing my jersey to him.
    My stock Junior pickup in my single cut is nice too. It's hard to find a crummy 90, but i have come across a few

    I just did the Gibson P90 thing and I found the full range of recommendations from 250 to 500. I went with what Emerson puts in their vintage classic 50’s set for Les Pauls. 500k, Bumblebee capacitors, .022 bridge and a .015 neck.

    The tone is warm yet not dark or muddy and on the other hand it is clear but not to bright. I’m really happy with it.

    I love double cut Les Paul Jrs and Specials. Having gone through a bunch of Jr. copies, I’ve come to like the 5os style wiring with a 500k volume and 250k tone pot. I use this on Dynasonic-type pickups on Fender style controls too. I use a .022uF cap with hotter P90s. My offset Tele with a Starwood bridge pickup and T-90 neck got a .033uF cap though, it’s a little more on the bight side, since the T-90 is underwound.

    I used std Strat 250k and .022uf for P90's in Fenders. Preferred it.

    I'm in as a 500k / .022uf for my P90s. I love the jangle.

    Is there somewhere that has 300K pots available? I believe they they are in an L6S I have but haven't found them listed at the usual suppliers.

    You could also try to open a 250 k and remove a bit of the graphit ... or - if you don't mind losing the option of silencing - put a 50 k resistor between ground and the pot's ground conductor. Or try out which works best: Connect a pot with a value above what you think will work - connect both hot wires, pickup and further, to the usual conductor on the hot end, and both ground to wiper - try what fits best - leave in that position, remove, measure, then you know the optimal value. You practically change the pot's value while staying at maximum volume then.

    It's likely the difference in sound between severely different values is much less than expected ... at least to me it was a surprise.

    So it sounds like almost anything goes for pot and cap values with a P90?

    Yep. Living proof of the statement “YMMV”. ;)

    Lots of people run Les Paul Juniors with 500k volume pot, 250k tone pot. That’s what I’m currently using in my Junior with a Wolfetone Meaner 90 and it’s pretty perfect.
