I am in agreeance with you all... I was just answering his question about could it be done.... and Yes... it could be done. SG's are thin and they are fragile and the most common (if only) way I know of having a Trem is by a Bigsby style Tremolo. I've seen guys that have done the floyd rose mods to SGs though... so I know its possible. It would change the tonal qualities and it would weaken the structural integrity of the guitar... but it can be done. If a good luthier is doing the job it would be done just fine. The only trem job that I've seen on an SG that wasn't a Bigsby and didn't change how the guitar sounded was a guy that used a Fender '83/'84 Strat tremolo. These tremolos... if you know what I'm talking about... Mount under the pickups without having to route all the way through the body. So I've seen it being done.... I don't recommend it by any means... I was just saying that it can be done. But what do I care, I hate SGs
