I'm trying to put a single coil, onto a cheap epiphone les paul. What im trying to do, is make it so the middle position, which normally blends the two pickups together, independent in a way, so that it can be used as a selector for the single coil.

Thanks for any help. If you need more details please ask, i appreciate it.
im not sure you can do that with a 3 way switch
i mean the one that comes with your lp at least im sure theres one that has room for three pick ups but then youd be better off getting a 5 way switch for more tonal capabilities
