Ok, so I was doing some pondering as I am considering my next build. I'm used to building neck through guitars and basses, and was thinking about bolt on necks, and was wondering about what if you reversed the orientation of the bolt on, and the slot for the neck to bolt into was on the back of the guitar? Maybe it extends to the point where the mounting bolts could be placed in the pickup holes, and the end slots into the body somehow. I've never seen anything like that, and there's probably a good reason... Thoughts?
