Gibson's Firebrand series "The SG" (or "The SG Std.") was a short-lived model that's developed quite the cult following, with a walnut body and neck, ebony fretboard, and a zebra humbucker pickup with exceptionally high output called the "Velvet Brick."

In the 1980 Gibson catalog, the Firebrand "The SG" Deluxe with mahogany body and neck was introduced, with all other appointments the same.
