    I'm about to replace the pots on my Epiphone '57 LP Jr. reissue. What do you think of trying 250K pots with the Lollar 5% overwound P90 I just installed? I guess you might get a slightly mellower tone which sounds like it may be a good move. One can always get plenty of treble, right? The original pots were 500K. Also, what's the hot setup as far as brand or level or quality regarding pots?
    thank you,

    Well my 92 Gibson lp special has 100k pots and it sound sweet! But I also have a tele with a 500k p90 in the neck and it sounds amazing.

    500K Volume, 300K tone works pretty well.

    as long as it's not a gibson 300k linear pot for tone.

    linear tone pots act like switches, making no difference until they're almost all the way off.

    I made a move to 250k on all my P90's. I incorporate vol bleed circuit for Spanky cleans.

    Using 500K pots in the guitar and turning the treble down on the amp is a poor man's Dolby (Dolby does it with expander/compressor chips, not EQ curves). But if you use pedals rather than power amp distortion - then you probably don't want to be processing the noise.

    Myself, I use 500K pots for the extra dynamics and turn the tone down to tame the treble.

    I used 500kA's in my PRS SE with Fralin's. When I roll back the volume I can turn up the tone so I don't lose highs. When the volume is wide open, I roll back the tone.

    I use 300K audio taper in my LP Special. Works well for volume and tone.

    Depends on what music you play, your amp set up, and what you're trying to achieve.

    When I used to play Santana-esque over-drive lead breaks I used 500k pots - to help achieve endless musical harmonic feedback sustained notes because there is virtually no loss in the pup signal. These days I play a lot of quiet clean channel toneful passages and I love the mellowness the 250k pots can bring... the 500k can be too harsh depending on guitar and amp set-up.

    I've heard about the 300k pots and will try them out one of these days. It might prove to be the perfect compromise for an all-rounder guitar.
