I have had that problem with the snare that came with my 66 Slingerlands. It just never sounded good. Last night I was determined to get it sounding good. It is a 5 1/2x14 3 ply, 6 lug. I ended up putting on an Evans G1 coated with an Evans hazy 200 on the bottom and a set of vintage wires. The best it ever sounded but still not great. Any suggestions? I wonder if the snare beds are off.
Ya know, I've come to the conclusion that not every drum "has it" and some just make for pretty display pieces. Those are the ones I pass on to "collectors" while I'd rather have the worn and good sounding ones.
