I've definitely seen him more recently with a semi-hollow Gretsch. I'm not remembering if it was live, live feed, DVD or what. Both that he uses/used have Bigsby tremolos are are similar enough in color to be confusing in stage lighting (red looks black in green light, blue looks black in green light, etc.)
Not that I want to own a Gretsch or anything like that. Does anyone have US$3000 they want to donate?
