Robert Plant and Jimmy Page (drummer and bassist of Deep Purple, Jake!)
But if you take away its testicles is it still a mudbucker? Maybe instead of Mud Jr we should call it a Unic-bucker Ive seen 5 including yours Uwe. This auction (2), Daves guitars in Wisconson(3) one in Malaysia with VVTT config like the latest auction popped up on the Gibson forum a few years ago (4) and mine (5). Mine has the l5 marking in the electronics cavity like this one as well as an Custom L-5 truss rod cover. I wonder if they had plans to call it that at one point but thought better of it. It does follow the pattern of being a styled after a hollow body like the L5S guitar.
