Geyer-style design provides ideal response and accurate intonation





The fabulous 10DYS boasts an abundance of traditional Geyer-style appointments. To start, its detachable medium-throat bell delivers a warm sound with plenty of color and excellent projection. Meanwhile, yellow brass tubing ? in a Geyer wrap configuration ? produces consistent, accurate intonation and an ergonomically balanced feel, making the 10DYS a treasure to behold and a pleasure to play.





Updated details for impeccable playability and easy maintenance





Like all Conn’s horns, the 10DYS includes a CNC-machined mouthpiece receiver to ensure the mouthpipe fit and venturi are consistent between horns. A standard mouthpipe water key makes emptying spit easy, and a brand-new adjustable finger hook allows players to achieve an ultra-comfortable grip. Paired with tapered rotors and valves, a corrosion-resistant yellow brass leadpipe, and durable yellow brass slide tubes, the 10DYS is designed for years of top-notch performance.
