I own a 1998 DW Collectors series kit that sounds great at lower tunings. What is it about some drums like Gretsch USA and Yamaha MCA that a lot of the jazz cats play and they sound really nice tuned medium and high? Is it just the edges? They all seem to have similar shell construction although DW has a thin re-ring, much less intrusive than old shells. I can tune my early 70';s Luddies pretty high but would like to to have a newer jazz kit.
