I bought a 85 explorer that is in the shop but I came across a cl ad for a 2019. It looks like the edges are sharper. It could be the angles of the pics or can someone comment if there has been a change.
85 was a few years before the reissues. Gibson made me the 2nd prototype about late 1989 / early 1990. The cut is slightly different on various models if you have them side by side.
There's a noticeable difference between the usual '76 and '58 reissue. I prefer the 58's which are a little bigger and less pointy. Those are the usual two styles, not sure if 85 is something different.
