im about to load a seymour duncan JB jr in my new highway1 in the bridge.
my question is should use a 250K or 500K push/pull and why?

I would go 500 unless you have an unusually bright humbucker. Keep 250 on your single coils. You may need to up your volume pot to 500 if its not already.

why up the volume to 500?

I may be wrong, hopefully another forum member can confirm it for us. But I believe the volume should be at least as high as the highest tone pot value. Otherwise it is like a bottleneck.

ok but th highest value is 250K.
looking on duncans sight some of the guys
said that they used 250K for this application because it made the pickup to bright sounding. why that happens i dont know. maybe big hair or ceri will stagger through and see our confusion and help out.
or nikki for that matter. i use to have him timed. i knew when he would be on or not. lol

WCJ, You can run that JBjr to your stock 250k Thats what I did and thats what that pickup is made for. A Strat so you can use the 250k and it will be just fine. Wire it up and if you dont like it you can always put a 500 in. I've got the stock pots and switch. No problems and it sounds fine.

Looking at some more diagrams from fender, it looks like they use 250s for many of the HSS models. I say go for it and see if you like it. What were you thinking of the push/pull for? coil tap?

The way I understand it, and I could be completely wrong. The increased resistance of the 500k pot lessens the bass response of the humbucker. Thereby giving the perception of a clearer sound by balancing the bass to the treble a little better. The 250k resists that less, making it more desirable for singlecoils that are treble strong by design.

Maybe look for a 330K or a 400K alpha pot? Tim Mills recommended 330K pots to me for my bare knuckle pickups.

Why not simply try both and see what you prefer? Or a 1meg pot, that may reduce some of what I found to be a problem with the JB.

Give it all a try. Pots are what £4 each. Spend £20 and learn what you prefer in that situation.

You're not going to create some wild particle accelerator and open a portal to the other side of some black hole by doing this bit of experimenting.

No no and no

High-value pots are stronger resistors than low-value pots, so they retain more highs in the signal to the amp.
If you switch from 250K to 500K pots, your guitar will sound brighter.
If your sound is muddy, you might try using a 1Meg pot to brighten it up.
For a warmer tone use 250K pots. That's always a good way to tame down single-coil pickups that are too bright.

good input kersen.

ok i went with the 250K non push/pull pot.
the sound was either way to bright or wasnt as powerful as the single coils
next to it. tried wiring it 100 out of a million ways and no luck.
these pickups are hot by design so something is seriously wrong. any ideas? on the duncan sight some have had issues with following the instructions and came out with the same results i did. others didnt have a problem. i dont know what anybody did to clear up the issues im having either.

here is what we are doing.

Have you tried switching the green and black wires (Green to switch, Black to ground)?

found this, don't know if it will help. "When wiring with fender pickups reverse the black and green. Black to ground and green to the switch."

did not see yours in time Shredd6

okguys, just because we tried so many different ways, i wanna say that we did try that but im not 100%.
why do you switch these wires?

You know.. I'm not really an expert about WHY. But when this kind of thing happens, it's the first thing I think about anymore. I haven't really wired any Duncan/ fender combos before. But even when I wired up a Lace Sensor pickup to some custom pickups not long ago, I had to switch the white and orange of the FLS to get them to work right together.

You know when something just sounds thin and weak, and that's usually the first thought I have anymore. "which wires do I need to switch up?"

Green and bare get grounded to the top of the pot, Black to the switch, and Soldier the Red and White together and tape together. Make your soldier connections are clean.
