Brand~C.G. Conn,Instrument Type~Double French Horns,New Arrivals,Professional,Sale Eligible

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.

This instrument is in exceptional condition. Ostensibly a demo model, I see no signs that this instrument was ever played. Includes original case and all original accessories, including hand guard, valve oil, and mouthpiece.
