false beats from??

The fundamental resonant frequency of the board is higher than that of
the driver (string hz), and overruns it. Adding mass lowers the
resonant frequency of the board so it follows the string as it
should rather than getting ahead of it.

Since the fundemental resonant frequency of any soundboard is in the 
range of 50 -100 hz depending on the particular assembly,  and treble 
strings fundementals are several quite a bit higher.  In fact, a quick 
reference to the following: 
http://www.speech.kth.se/music/5_lectures/wogram/modal.html  shows that 
even the 8th mode is significantly lower then the fundemental frequency 
of A5.


I can only assume the above quote is not exactly what you meant to say.
