  Maybe gluing the bridge cap on in the crowned position and the bridge =
to the sound board in the crowned position, like Dale does, will add the =
necessary impedance to the treble end of the bridge.=20
It's not the treble end of the long bridge that is in question here. =
It's the bass end of the long bridge. And no amount of crowning the =
bridge to match the crown of the soundboard is going to affect that. Or =
much else, for that matter.



  Most of the models discussed here on the list, didn't seem to deal =
with the  stiffness added by the glue joints in a laminated structure. =
Usually underestimated and throws that kink into the reality/theory gap =
along with a few of the other observartions Dale has made.
Would you care to explain this a bit more? How does stiffness added by =
the glue joints in a laminated structure -- assuming there is any -- =
affect the impedance of the very end of the long bridge?
