Right so. I know I can put in a push pull to turn on a pick up. But

1. Can i turn OFF a pickup that way and if so...

2. Can i wire 2 pickups to the same off switch?

3. If i can do either, can someone write me up a diagram?

I am ordering a Les Paul Black Beauty (3 pickups) and i want Jazz/Phat cat/ JB, but with the wiring thusly

3 way switch as standard les paul (bridge/both/neck)

neck vol - split neck

Bridge vol - Split bridge

Neck tone - Turn on Phat cat

Bridge tone - turn OFF both humbuckers

Fender Lite Ash Tele

Satellite 65/T

Yamaha RBX375
^ I have to say, that is a really great way of wiring a 3 pickup LP as it gives you so much variety.

You'd get great advice and and loads of help, aswell as all the info you need to make the diagram yourself in https://www.ultimate-guitar.com/forum/showthread.php?t=1019006

Read up and then if you're stuck, post for help in that thread

In future just search for like a topic thread

The answer to your first two questions is yes by the way
