Most other band instrument owners seem to be content with the traditional band line of Besson/B&H derivatives, but the trombones often show an independent taste. If you're a trombonist, what make and model do you play on? Have you deliberately selected that instrument? What bore size is your instrument? Have you consciously selected that bore size? Why? My advance guess for the poll winners is: Tenor: Conn 88H, with Bach 42B in second place Bass: Holton TR181 (but not by a large margin) For my part, I play tenor on an 88H (.547" bore - large size), and bass on my shiny new Conn 62HCL (.562" bore - bass size). There are far more available options than a poll can show - so please add a post, and if the poll becomes unrepresentative, then I can tally up the results by hand.
