Gibson makes basses that people seem to either love or hate, for whatever reason. I really want to love the SG model, but the body feels a little too small for me (6'2", 230lbs) and I don't get on as well with short-scales. They look and sound beautiful, though. The T-bird is another monstrous sounding bass with a great look, but I like a neck with more width at the nut. I had a new model EB4, and it sounded good and was lightweight, but I just never bonded with it at the time. A lot of people love that bass , so I can't understand why Gibson discontinued it. They did put the EB4 pups in the 2015 T-Bird, though, so I guess it kind of lives on in that model now. I agree with Tbird58, Gibby's walk their own path, and for some players nothing else will do.
I still may pick up a used SG down the road, though, and the Midtown Classic/Signature is drop dead sexy...........
