Hey, I've just hit a real snag in my restoration of a 1971 Gibson SG Deluxe. These normally shipped with what is labeled as a 'Gibson Bigsby' bridge, and this one is no different... but I was given it without the bridge, so I ordered one in to the store I work at. But I ordered a B5, thinking that it took the same bridge that all other SG's use since the beginning of time. Not so much. It doesn't fit; does anyone know what model of bridge actually belonged on this guitar, as well as whether or not Bigsby makes them? Thanks, guys; I'm going nuts here!
