push/pull pots - what role do each prong play on these?


On push/pull volume/tone pots.....what is each prong responsible for?
Take the Ibanez Js push/pull circuitry: what do the six prongs do on the
bottom half of the pot, and what do the top three prongs do?
I need a better understanding as to why certain wires are soldered
to a specific prong, and why capacitors are soldered the way they are
on the Ibanez JS1000.

I look at the wiring in my Js1000 and all the wires are tangled and
soldered everywhere, and i'm just confused as hell.
Some prongs dont have any wire soldered to it.

Can someone explain in easy-to-understand english, the story
behind all those prongs??

push/pull pots


Think of a push-pull pot as a pot with a two-way mini-toggle switch grafted onto it.

The top three lugs are for the pot's turning function (volume or tone) and should be wired just as any other pot. The bottom six lugs are what you would find on any mini-toggle switch, and would be wired as such to get coil tapping/splitting/phase switching/series-parallel, etc.
