I always liked the story about the Olds Mendez model. They cloned Mendez's French Besson, and Mendez was totally unimpressed, until they valves were lapped down to the point of being leaky, just like the much played Besson. Too often when trying out a new horn, we want it to be just like our old one, only more so, and are often disappointed. Only if we allow the instrument to seek it's own voice, can we truly say that we've tried it out. p.s. Jens, welche Alarmanlage Hersteller?
