Re: The Buddy Rich sound
By most accounts I've read Buddy used Emperor heads with ambassadors for resonants, but, sources on the net are not always so reliable. From what I've seen on DVD's and the like Buddy's sound wasn't always the same anyway. Switching from Slings to Ludwig to Rogers and back and forth. Also changing bass drum sizes from 26 to 24 to 22 and back.
I think the main thing about BR's sound is the fact that nobody sounds like BR.
