Can anyone tell me the thickness of the thinest point of the belly contour on an original NR Bird? In inches, please? I have a Red TH-1 with no body contour and I am seriously thinking about attempting to carve one out but I was wondering how deep to carve out. Even better, if someone has specs of the body contour in general that would be great. If that makes sense. Basically, when looking at the back of the bass, how far in do I go from the right of the bass? And how far down from the neck pocket, etc? Does any of this make sense?
