Conn 10DY Professional Geyer Wrap French Horn is a professional double horn built in the Geyer tradition, combining yellow brass construction, a small-throat 12” bell, and a direct-soldered mouthpipe for a warmer, more solo-oriented response than Conn’s classic Kruspe-style 8D lineage. Developed as a modern evolution of Conn’s professional horn design, the 10DY uses traditional Geyer taper, a .468” bore, string linkage, and a reversible fourth rotor to support advanced orchestral, chamber, and solo playing with comfortable resistance and clear tonal center.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eC.G.

Conn 10DY is a professional Geyer-wrap double French horn designed for advanced students, collegiate players, orchestral musicians, and soloists who want a Conn-built horn with a warmer, more centered Geyer-style playing profile. Its yellow brass construction, small-throat bell, and traditional Geyer taper give it a focused response with comfortable resistance, making it suitable for players who value tonal color, flexibility, and refined control.\u003c\/p\u003e\n\u003cp\u003eWithin Conn’s professional horn lineup, the 10DY is distinct from the classic 8D concept because it follows the Carl Geyer design approach rather than the broader Kruspe-style tradition. The direct-soldered mouthpipe is a significant design feature: because the mouthpipe is soldered directly to the bell rather than braced in the conventional way, the horn has a different resonance pattern and response feel than many mass-produced professional horns.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCommon Questions About the C.G.

The 10DY’s yellow brass body, small-throat bell, traditional Geyer taper, and direct-soldered mouthpipe produce a more focused and warmer response compared with the broader 8D-style concept.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eCan the fourth rotor be changed from F\/Bb to Bb\/F?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eYes. The C.G. Conn 10DY has a reversible fourth rotor, allowing the player or technician to configure the horn for either F\/Bb or Bb\/F operation depending on preference and playing background.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.quinntheeskimo.net\/Pics\/connlogo\/connlogo0.jpg\"\u003e\u003cimg style=\"text-align: center; display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/www.quinntheeskimo.net\/Pics\/connlogo\/connlogoThumb0.jpg\" alt=\"Conn Logo\" align=\"Middle\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eWe are proud to be an authorized C.G.
