Hi, I just brought a 500k Push Pull pot. Meaning that when you pull it you can turn it or when you push it in you can turn it.This is so you can have 1 pot for two functions I guess. Ill attach some pictures. Im just wondering how I would wire it into the circuit :) Thanks.

I'm not sure if I understand what you are describing. But that looks like a 500K pot with a push/pull DPDT switch.
Think of it as a normal 500K pot and a normal DPDT switch that only require a single hole. The switch and pot are electrically independent.
What circuit do you want to put it in?
I've never seen a push/pull pot with that function. Wouldn't it be that the switch is a completely independant entity and the pot still only controls the same thing? Thats how it is with the only push/pull I've ever seen/used - it splits or combines the two coils of my humbucker, but it still controls the same thing no matter what position it is in.
One popular application for those is to replace a volume or tone pot on a Strat with the potentiometer portion, and modify the 5-way switch wiring to use the DPDT switch to allow the bridge/neck pick-up combination and bridge/middle/neck pick-up combination.
Both of my guitars have one of these in the tone pot position, for splitting the humbuckers to single coil.
I've only seen them on a few pedals, namely one of the Barber "Drive" something-or-other. Direct drive?
EDIT: Yes, the Barber Direct Drive. (http://www.barberelectronics.com/directdrive.htm) Pulling up on the tone knob switches in the "Fat Harmonics" mode.
Anyone have a part number at Mouser or digikey for a 500kA pot like this with a DPDT - I'm looking to put something like this on my guitar as a volume/coil split.

I put those style pots in a Squire Esprit, so you could split the coils with the switches - a nice function! All humbucker'ed guitars should have that feature and take a leaf out of the yamaha sg book. It gives the instrument a whole new range of sounds making it more versatile. Its a shame my gibson sg has just a "hot" and earth coming out of each pickup; i'd definately mod it if the coils had independant cables coming out. I suppose you could break into the pickup to do it, but I fear I'll damage the coils or something. Shame, because I like the gibson pickups, and coil splits would be great!
Also, Gibson's HB pickups sound pretty awesome in SC mode - but ya, you have to be careful modding pickups. The best way to go is to just get a set of Dimarzios.
