So I have a 72 Ludwig player I use for light blues and jazz gigs. 18 and 20 bds, 12 and 14 toms. The 12 Tom has always given me trouble. It has a very small tuning range. If I don't get it just right, it's sounds choked and lifeless with no resonance. The drum has a RIMS mount with a Yamaha bracket. The other drums are awesome. I recently had the 18, 12, 14 re-edged hoping that would help. It opened up the bass and floor Tom, 12 is still bad. It tried other hoops thinking maybe they were bent, nothing, many head combinations, the wrap isn't too thick', heads spin freely. I hate to part with this kit. It's a player grade, has great mojo and the other drums sound great. Any ideas of what it could be? Is it just a dog?
