It really is, "Just one of those things". I played Gretsch round badges for some 30 years and they DO sound very nice. But not twice as nice as Slingy or Ludwig or Rodgers from the same era. The toms have a nice, full, warm sound, but in truth, I never thought the snare drums sounded all that great. Slingerland, in my opinion, always made the best sounding snare drums.
In general, with all the different brands I've played over the last 40 years, I have to say the best sounding was a set of 1941 Radio Kings with calf heads. Another drummer on the same bill as me let me use them. It was a big thrill to get to play them.
Those things thundered, with the nicest tone I've ever heard. Wish I could afford a set of those!!
