BT, I never consciously worked on my sound, and yet arguably, I have a good sound, and it is "my" sound. My thought has always been that unless you have specific tone-related problems, there are other things to focus on. This isn't to say that things like long tones or breath control concepts should be ignored, but only to say that we shouldn't over-think it. I always thought Bud Herseth's sound was as much like like a lead big band trumpet player's as anything else - big, but also fat, brassy and bright. Is that what you mean when you say "a particular sound that orchestral players tend to have?" I ask because Bud seems to be the guy that so many have tried to emulate.
