According to Uwe, most likely the underlying reason for the Hammerschmidt’s—both alto and tenor—intonation problems, is that the company copied an old version of a neck. This neck had been made of soldered brass. The new Hammerschmidt neck however, was made with brass pipe material that was blown as one piece. Therefore, while the external dimensions were correct, the internal ones weren’t. On the end closest to the mouthpiece, the brass was too thick. While on the horn end of the neck, the material was too thin.
