I know there is much discussion about the difference between 3-ply and 6-ply Ludwigs. I restored these from orphan 6-plys and used these in the studio and they sang. I am on the side of the fence of 6-plys can sound great. I did have to give some attention to the edges in order to get them to tune up well. Here are specs:
9x13, 16x16, 16x24. Kick is a virgin with the dual spurs. Refinished in black glass glitter. Emperor coated on top, Ambassador coated on the bottom. PS2 coated on the batter kick, medium original Ludwig head on the reso side.
