When and WHY did PRS go to that VERY LARGE BULKY uncomfortable neck heel?

A. 1995 -- PRS went to the new longer neck heel to improve the strength and tone of the guitar. When you reduce the length of the neck you increase the strength by its cube (x3).

When you increase the thickness you increase the strength by its square (x2). The playability of the guitar is opinion based since we have found no problems with this de more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
