I think we've seen that Joe B picture before, he must have quite a few more by now - including more of his own LP signature models in the new sunburst colour.
I hadn't heard of Keith Richards having 3000+ guitars, that sounds a bit extreme (unless that was just a "big" number plucked out of thin air?

), but he certainly has a lot, as do Billy Gibbons and Rick Nielsen already mentioned. Then there's Joe Perry, and Steve Howe, and John Entwistle (RIP).... I think some of those guys may have had clearouts over the years though.
Oh, and Phil King! :P
