F/Bb Double Horn · Model 1104
The double horn has established itself as the orchestral instrument of choice. The combination of full Bb and F horn offers the musician great flexibility in intonation and tone. There is also a definite correlation between mass and tonal projection. With full double horns the thumb valve serves to change to either the shorter Bb horn or longer F horn.
Modell 1104 is manufactured with an extra thumb valve in E/A, that with the addition of an extension can be used as a stopping valve.
