On my 14x16 Premier Signia hanging floor tom I decided to lacquer the inside as it was raw. I was thinking I was being nice to my drum protecting it from the elements. Ok..it dries and I put the drum back together. I hated the results acoustically. Bob Gatzen was right. I'd forgotten his words on doing this procedure but he was right. Lots of sanding taking it back off. I kept thinking to myself....you idiot!.
