stopper screw.
Wind the string around the screw in the same direction that the screw tightens. After winding, use
the String Stopper Screw B to adjust the lever's height.

F/Bb Double Horn
The Yamaha double horn is designed so that it normally plays in the key of F (open F) when the 4th
lever is not depressed, and in the key of Bb when the 4th lever is depressed. However, by re-configur-
ing the linkage as shown in the illustration below, this function can be reversed so that the horn plays
in Bb (open Bb) when the lever is not depressed, and in the key of F when the lever is depressed.
To use this setup, move the string and the string seat, then place the string over the string seat.
