The AC420BO is a Bb/F Legend Series trombone for symphonic playing, built around a .547-inch bore and an 8.5-inch one-piece bell. The bell is specified for projection and response. Its open-wrap F-attachment uses a standard rotor, with mini ball linkage for smooth action and an adjustable thumb trigger to tailor the operating position. It has a standard fixed yellow-brass leadpipe and standard-weight yellow-brass handslide. The lacquered instrument includes a mouthpiece and lightweight contoured case.
