    The only wiring that makes sense for me is one with master vol/tone because I don't like jiggling with two vols. Especially with single coils where you're rewarded with hum when dialing in "your" tone (same with blend pot). So that leaves a hole on the control plate which I filled with a dpdt switch to toggle series/parallel. I used 250k pots which are totally fine in parallel mode. Series is darker, bassier and while I like it when playing with a pick and the attack you get, it's a little dull when playing with fingers. So I thought why not put 500k pots in it to brighten it up. I could still get the 250k sound by rolling off on the tone which I always leave on full right now anyways.
    What do you guys think? Also something I never quite understood is what you get when you change just one pot. What's the sonic difference between changing the value of a tone pot as opposed to a volume pot (or the other way round) and leaving the value of the other pot the same?

    You can easily test what it would sound like with less load by just bypassing the pot for a test.

    So, both your pickups are always "on" the same amount? You can never solo either pickup?

    I've never heard of anybody doing that mod before. I don't think I have ever played one of my Js with both pickups on full, other than just to try it and see what it sounds like.

    Yes both PUs always on full. Either in parallel mode or in series mode like a humbucker.

    500ks would make sense for that. you'll want linear volume and audio tone.

    using an open or "no-load" tone pot will give you just a hint more treble too.

    I have a p/j that I put 500k on. It sounds a hell of a lot better than the stock pots. And I bypassed the tone altogether. I think it sounds great.
