Hey guys, i also have a 1980 Gibson sg Firebrand.It is made out of Mohogany,Gibson is burnt into the headstock and Sg Firebrand is inscribed onto a piece of plastic on the headstock.The body and headstock are burnt with what looks like little T,s all over, and its got 2 double hummbuckers .One of the Hummbuckers is a Zebra(half black,half white)The other is just solid black.I love this guitar,the action is about the sweetest ive ever played,and the tonality is awesome.I know very little about the guitar, so if anyone out there has more info on it,I would be happy to hear from you.
