Re: Variable phase?
Not too sure how it would work but what I'd like is
OOP at one end, in phase ot the other and variable from in between.
Thats why I'm thinking a blent pot, a bit like the "spin a split" mod.

It might be possible using a stereo pot, but i dunno

Re: Variable phase?
Yore wrong. it's merely a matter of reversing the two coil connections. A stereo pot should be able to do it.

"You're wrong", anyway, if you're that confident, I'd be interested in seeing a diagram for "variable phase".

Re: Variable phase?
It doesn't work like you'd think. It ends up being like a combination volume control and phase switch. One half of the turn is in phase, the other half of the turn is out of phase, and it turns the volume to 0 at the center crossover point. But that variance can be useful, however. For example, on my SG right now I have the Jimmy Page wiring and the best out of phase tones are where I turn one or the other volume down slightly so they are relatively out of balance to each other. So this phase blend might be an interesting idea for a guitar that only has a master volume, rather than separate volumes per pickup.
FYI - I tested this by using alligator clip wires to attach a pan/blend pot to a 498T, then coupled that output with a 490R to a single instrument cable into a powered monitor and tap tested the pickups with a metal knife resting across both pickups and tapped it while turning the knob.

Re: Variable phase?
I'm wanting to use the wiring in this link
https://sites.google.com/site/phostenixwiringdiagrams/strats/strat-x
I't seems to be hiding the actual diagram but I do have a few printed copies somewhere.
It's basically for a strat with master vol and tone and uses an S-1 switch to give
10 postions, the five normal and all the other series, tele mid and all on.
I love the tele mid in series out of phase option and keen to experiment with the other phase options.
If it can be done, I'd apply the second tone pot.
Cheers, Will
Most interested indeed!

Re: Variable phase?
My bad. Yawn wrong !
Will you make a graph of it ? and improve the design ?

Re: Variable phase?
What value pot did you try ? Also hacking the pot to no load would probably get rid of the volume effect.

Re: Variable phase?
Why would you want a graph? You're not making sense to me. You had said I was "wrong", and I'm just asking you to elaborate. It's a straightforward and reasonable request.
OP asked if there was a way to get "to get variable phase", specifically, "[out of phase] at one end, in phase at the other and variable from in between", ... his words. What you and others are talking about with a stereo pot, or dual gang pot, would be able to switch the phase, but only achieve a "variable amount of volume", and act as a typical blending pot. It would not achieve a "variable amount of phase", as phase is either "in" or "out", and cannot be a blend of the two at one time. IMO it would make more sense to simply use a push/pull pot in that case, for simplicity sake and availability of parts.

Graphs are an important part of our every day life. It may not seem that way, but without graphs, we would be lost in heaps of data. Without even knowing it, important decisions are made daily throughout the world based on what a graph can tell us.

Re: Variable phase?
You apparently don't know the first thing about mixed signals.
And how, exactly, would a push-pull pot achieve "variable" anything? That's an on-off switch, my friend.
Leave the electronic advice to those who actually understand electronics, please!

I used a CTS 500k Balance/Blend pot, from here:
