Independent shopping perspective
Conn’s CHR511 is an intermediate double horn built around a Geyer-style wrap and fixed bell. Its CNC-machined leadpipe and mouthpiece receiver follow Conn 11DN specifications, joined by a nickel-silver leadpipe and a small yellow-brass bell throat. The reversible fourth valve allows either F/Bb or Bb/F configuration, and string-linkage rotary valves handle the changes. Brass construction carries a lacquer finish, while the adjustable finger hook lets the player set hand position. A protective case supports storage and transport.
