impedance

[Richard Brekne]

You are attaching to the bridge pin itself... the fact that you are 
attaching to the back one and still get a very large affect, while 
neighboring strings are unnaffected / perhaps only barely affected is 
interesting in the face of some of the discussions surrounding string / 
soundboard vibrations etc.  Localized impedance problems themselves migh 
be explaned by the resonance frequencies profile your particular board 
has.  Re-read through some of that Five lectures stuff Dave. Always 
great fun.

I am aware of how to deal with the problem--mass substituting for
stiffness, etc..  The question is, why does it happen right in the
middle of a section of the bridge so that it could be avoided in
soundboard or rib design or placement.
