I have a walnut SG. Gibson made it in 1979, and the model name is just "The SG." I love that guitar more than anything else I own. My older brother bought it from some random guy in 1983, played it for a few years, then sold it to me in 1987 when he got distracted by a red Jackson Randy Rhoads flying V. I've been playing the SG ever since, nearly every day. There's nothing fancy about it, it's not collectible or worth a lot, but for me it plays better than any other guitar I've ever played. It's got a fast, thin neck and low action, just a dream to play. It's sitting on a stand right behind me and if I get a chance tonight, I'll play it until it's time to go to sleep.
