As light or lighter than a normal double horn, the Bb side fully comparable to that of a double horn, and can switch to high Eb without a change in sound. (When you change from Bb 0 to high Eb 2/3, the Instrument is only shortened a half step) A surprisingly good combined low F-horn. Because of the correct placement of the recommended 4 water keys, they cause no acoustical disadvantage.
