Ohm value of Gibson tone pot?

mid_life_crisis · 07-21-2010, 06:54 PM

Classic Fenders have a tone pot that is a dual pot with a center detent. I'm thinking about getting one for a project but need some details on them. Does anyone know:

1) The impedance of the pots?
2) Are both pots the same impedance?
3) It seems reasonable to assume that the center detent is half the value of that impedance, is this correct?
4) Are the two pots electrically isolated from each other except for the shell? That is, could you use them for more or less unrelated portions of the circuit and not get cross talk?

Thank you

Do you have a multi meter?

Are you talking about guitars or amps? I've never played either that had a tone pot with a detent.

If you're talking about guitars, and more specifically guitars like the Les Paul with dual humbuckers, they usually have 500k tone and volume pots.

I suggest going to Seymour Duncan's website and check out the wiring diagrams there.

As far as guitar pots they are pretty much 250k and 500k although some folks upgrade to a MB but I have never seen a stock guitar with one that high. Strats off the shelf usually have a 250k..
