I'm sure the same was true with sticks as well. Although Vic Firth Buddy Rich models are nice, I'm not sure how 'signature' they can be since they came out after Buddy's time. I think Donny uses ProMark now. I think it's amazing how much he resembles Buddy, even the way he sits at the kit. Anyway, a lot of jazz drummers today are using Regal Tip brushes (Jeff Hamilton, Clayton Cameron to name a couple) I wonder what Louie Bellson uses, or even how much playing he does anymore... Ed Shaughnessy is a ProMark endorser although I'm not sure what kind of brushes though, same with Joe Morello.
