I am interested in the differences in top carves of the Les Paul Customs. I have a 68 reissue and would like to know about the top carve that Gibson has used on the different years of the Customs. Like the 57 custom and the 68. Then the Norlin year guitars. I never really paid much attention to it before. When I got my first LP back in 79 I was like 16 and thought that all LP's must be the same other than the differences in trim. Then through the years I started learning that they all are not the same. I would really like to know more on this subject thank you.
