This 1986 SG turned up on eBay, and the seller says it is a "61 Reissue" model. In fact, he says that 1986 is the year Gibson first introduced the 61 Reissue. Is that true? The most unusual features are the edge-mounted output jack, and the odd location of the pickup selector switch. And yes, it does have a small pickguard. But it doesn't have the "stepped" neck/body joint like a 61 Reissue. On this one the neck blends smoothly into the body contour on both sides. I think this is an SG Standard, but I've never seen a Standard (or a 61 Reissue either) with a side-mounted jack. Also note the trapezoid inlays. Were those used on Standards in 1986? Of course, the key question is: When WAS the 61 Reissue introduced? So ... what IS this thing?
