it has only 2 control knobs not 4 so its not a true "SG style" looks like a SG Diablo? shame we cant see the head stock. It also has a full maple neck as well, very rare for Gibson to do that. Only one I can remember off hand is Zakk Wylde' Les Paul.
EDIT
Shame its not a Gibson Angus Young Signature SG autographed, that would get you a very good new scope
I have been looking and my money is on this not being a Gibson Guitar.
