I bought this guitar about 6 months ago and it plays beautifully. nicer than most sg's I have played. I never really noticed this until the other day but the control cavity is routed through the front instead of the back of the guitar hence no backplates at all. I looked up the serial number and it is apparently made in the early 70's. I'm pretty sure the original finish is stripped back but I have never seen an sg with no backplates. Not sure not if its real or fake does anyone know? most of the hardware isn't original and I put the new tuners on. Thanks a lot, Rory.
