Please tell me if this idea has already been done, but I had a wacky idea a few minutes ago that I thought might work and might be somewhat nifty. Here it is. So, what you would do is glue like 5 or 6 jazz pickups together and then wire them so that you can have a switch near each pickup to turn it on and off. With this, you could have almost any j/j, hb/hb, hb/j pup combination. To get sort of a "humbucking" dual coil sound, you could turn on two pickups right next to each other. I don't have the money or the time to do this right now, but if someone wants to try, feel free. Just a thought.
