I ended up with this Bournes pot, www.tubesandmore.com/a push-pull with dual resistors but just one knob. Also the resistance is the same for both traces. It's not a blend pot. What's if for? I have been mixing humbuckers with SC pickups on teles, so if this could be jerryrigged to make it easier to go from 500K to 250K and wire up differnent tone caps, that would be probably be worthwhile. I guess I have not actually seen these in use. Ideas? |

52 blue- Hello and Welcome to G-Nutz2! Unfortunately, your link is not to this particular part, but to the Antique Electronics Homepage. So I can't tell you anything . . .  |

Aha! Good find, 52! I had not known that these existed.
This is a dual-gang Push/pull pot. The Push/pull portion is a DPDT switch, it can be used for anything a regular DPDT switch can do- series/parallel, coil cut, etc.
The dual gang control can be used in a number of ways. JohnH has a "Strat with 2 volume controls" design that uses a dual-gang pot as a master tone control for two pickups with separate volume controls.
Use of the dual-gang pot for the tone control allows each pickup to have its own gang of the pot, and the tone can then be placed before the separate volume controls for each pickup- the controls are wired just like a Les Paul, except both tone controls share the same shaft.
I'm building a stereo Tele that uses a dual-gang pot for the tone control, as each pickup has to be separate for channel separation.
A dual-gang pot can also allow for separate tone caps (perhaps for different types of pickups) to be used on a "master" tone control.
Dual gang pots can also be used for blending, in various ways.
It isn't surprising that both elements are the same resistance value, that's what one would want for tone control use.

Its good to know about that pot - a new block in the box of Lego bricks! It seems like a good price and hopefully it actually fits in a guitar too.

doesn't look any bigger than the regular bourns push/pull pots, of which i have at least one in every guitar i own
(in fact i only use bourns pots)
the only problem is depending on the pot (and i have yet to determine which is which), some are way too easy to turn. the others have a decent resistance when you turn it

Well, I switched one of the carbon tracks on a 250K and 500K to have two to put before the blade switch for separate tone pots on teles with one humbucker and one single coil. ... Hope it works okay. Easy to do, except need to be just a little bit careful not to mess up the push-pull when you pull it apart.

You could turn it into a centre-detent-less pseudo-blend pot that way, I would surmise. |
