Re: push-pull
It depends on a few things. What do you want to do with the push/pulls? Split the pickups? Phase? Series/Parallel? Also, these can only be done it the pickups you bought are 4 conductor. I know that the 59 can be either 2 wire or 4 wire. Look at the wires coming out of the pickups. If there are 4, then you can do one of the above with a push/pull pot. If there is only one wire with a metal shield around it, then your out of luck.
hope this helps,
