I have been wanting to try out some different pickups and control layouts, so I am building a hard tail dedicated to that. The rear access plate will allow pickup changes without loosening the strings. The pickup cavity is sized to allow P-90s, or anything smaller. When I want to change the controls around, I will just plug the holes and re-drill. You may be able to see that I have already plugged one hole as I changed my mind about switch location. Since this will always be a work in progress, I used no fancy wood, and I am not going for the ultimate in cosmetics. I did do my "gut cut" rear contour.
