Toru Kikuchi from Nodame Cantabile plays the Cello. Sakura Saku from the same anime/manga/live-action plays contrabass (not sure if that's comparable or not. I don't know too much about the string section being in woodwinds myself =P)
Gauche the Cellist from the anime with the same name is also one.
Hamel from the Violinist of Hameln plays a violin, but it is often mistaken as a cello. You could pose with a cello instead of a violin to kind of bank on this joke. It's because his violin is VERY large =P and realistically would be the size of a cello.
