Jpatryas66: Welcome to SOTW.
Yes, I have one (for alto) but don't recall how it came me . . . maybe with some horn I bought a while back. If the mouthpiece plays for you, then it is a good one. Declaring any mouthpiece to be BAD is foolish - we all differ. There is a thread somewhere on SOTW about a great $12 mouthpiece - I suppose, if it plays for the person who tries it.
As far as value goes, I doubt if the Belmonte is expensive when new, but who knows? I don't care for it, but maybe someone else would. DAVE
