FDP Forum / The 'Pup' Tent / Push pull split coil pups

I have a fender player series tele HH with split coil push pull pot. Curious as to the pot value when the rule is 500k for buckers and 250 for single coil. So what pot do they use to work with both in a set up like this?

500k is good. You can always roll back the tone a little in SC mode.

That will work, but if you really want to know what's best, try it both ways. Your ears and the amp you play through also are part of how the pickup will sound with different pots.

The reason is some humbuckers need a 500K pot and some don't because they're an inherently bright pickup.

One of the pots will work better and sound better to you than the other one.



Why do I keep fixing things that work?

I know somewhere I saw a push-pull pot that when engaged (down position) it was 500k ohm and when pulled, it became a 250k pot. I just can't remember where it was. But regardless, wouldn't that be ideal for this kind of a setup? That would address both positions equally well and have the proper ohmage for both settings.
Do a Google search and you may find it.
I'm not sure if it was Dimarzio or Amplified Parts but it came up on a search that I did a while back.
And if such a part would be available, would you use the proper ohm capacitors on each leg of the hot lead going to the pickup selector and when engaged in each mode the pickups would have the proper resistance? Just a thought but would be cool if for this very same kind of issue that I see often here.
Is my thinking on this correct?
Thanks, Woody

There really is no rule, it just depends on what sounds best to you. Some people split the difference by using a 400K. A little harder to find, but available.

I would be inclined to start with a 250K and change to 500K or 400K if the tone was too muddy in full humbucker mode.

If none of those solutions satisfy, another option would be to start with a 500K DPDT push-pull volume pot, then employ the second pole on the DPDT to switch in a 500K fixed resistor in parallel with the volume pot when coil split is engaged. That way you have a 500K in humbucker mode and a 250K with slightly altered taper in coil split mode.

But I would try one of the simpler options first. All the above assumes that your switching is like the American Tele HH, where both coils are split at once, no positions with mixed split and full humbucker.

Definitely, there is no rule on what to use.

250k or 500K... both can be fine-tuned with the cap value.

Being a single coil guy I prefer the 250k though.

I have in my possession (that I sue a lot) one of those Fender USA "Professional" Telecasters HS with the split humbucker in the bridge. 500k pots

It has a great humbucker that when actually split it sounds like an actual telecaster bridge pup w/ twang and all. Adjustable pole pieces great pickup.
