For years I've played with a hot humbucker in the bridge position and not spared a thought for anything else. Recently however, I've been learning about how different tones are created with different styles of pick ups placed in different positions.

I've discovered how awesome P90s are and want to experiment. Also, I've come to realise that Hendrix's lead tone more often than not came from a single coil neck pick up.

Naturally I thought about getting a kit guitar and installing some magic combination of pick ups. The conflict began with not being able to let go of the idea of a humbucker in the bridge. If I keep that, and want a single coil in the neck, how do I implement a P90?

So I'm thinking I want a guitar with a humbucker in the bridge, P90 in the middle, and single coil in the neck. Possibly a Fender scale length so the pick ups can be reasonably spaced apart.

Does such a beast already exist? Can I buy one off the shelf?
If not, what would be the easiest kit to do this to?
