The vintage instruments of Carl Geyer are revered for their sound, construction, and design. The all-new Conn 10DY embraces that tradition 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.

The new mouthpipe taper gives a comfortable resistance, requiring less effort from the player and enhancing endurance. The small-throated “Schmidt”-style bell has a compact sound that projects effortlessly to the back of the orchestra hall. The 10DY is equally at home in chamber ensembles where the warmth of the all-brass construction blends with strings, winds, and brass alike.

The essentials of Mr. Geyer’s timeless horns have been preserved, with modern design processes only lightly touching the 10DY. CNC-machined mouthpiece receivers ensure exact mouthpiece fit for optimum response, new manufacturing techniques create a more consistent instruments, and the addition of an adjustable finger hook and mouthpipe water key make performance more comfortable.
