Conn has been making some of the worlds finest French horns ever since they introduced the 8D back in the 1950s. The 10DY is a natural evolution in the process, bringing yellow brass construction and the Geyer configuration for a warmer more soloistic kind of playing experience. The all-new Conn 10DY embraces the tradition of Carl Geyer with its cartridge brass construction, unique mouthpipe, and century-old bell dimensions. With a mouthpipe that is not braced but directly soldered to the bell, the resonance and response of the 10DY are dramatically different from any other mass-produced horn.
