The SG body shape has always been "love it or hate it." Not sure why. Works for me, that's all I care about.
I like everything about them except not so much for the way they actually look. As for people hating them, probably a lot of the time that's from people who have an overall bias against Gibson itself. At least that has been my impression through the years. Of course there are people who are going to be critical of short scale basses, what they consider a muddy sound, etc,, regardless. Personally, though, I think Jack Bruce made EB-3 basses legendary, although I'd like them even if he had never played one. Of course if Gibson itself felt that way, they would have brought back an actual EB-3 reissue long ago. Something which apparently wouldn't be considered marketable in today's world, though.
