I want to build a guitar from parts, I've figured out most things but I can't find a reference on placing the pickups. To further complicate things I'm putting a 24 fret neck on a body that was routed for 22 frets. This will blow away the neck position single coil pickup. My investment in the neck and body is minimal so if I destroy it that's not a problem but I'd eventually like to be able build one out of better parts.

So how do you place the middle and bridge pickups? Why are some bridge pickups angled? (This one was originally)
