Nothing odd there. As I recall, the top several octaves were retro-fitted with phoenix agraffes. One would expect the mass of the agraffe to increase impedence on those notes. Sauter gets similar effects on their top line instruments by using ebony bridge caps and titanium bridge pins. Petrof uses three different woods in high treble, treble and tenor bridge caps to modulate the impedence. It would be nice if we had some kind of impedence dial to voice the bridge, note-by-note. Ed Sutton Fred wrote: Could be, but that doesn't explain how putting some agraffes on a standard bridge makes _those_ unisons sustain so much better than the standard neighbors, as in the Baldwin retrofit shown I think at Grand Rapids. Or did that other list address that seeming magic as well? Regards, Fred Sturm fssturm at unm.edu “Art is not a mirror held up to reality, but a hammer with which to shape it.” Brecht
