Soundboard Thoughts

[Horace Greeley]

Danny,

This kind of fix is going to vary in effectiveness
on many different parameters.  But, there is 
every reason for it to work.  Questions are
going to include things like:

What's going on in the "dead" area of the
soundboard?

Does the width of the toe of the board allow
a lot of, or discernable standing wave distortion?

Is the board "bound" between the top of the
bass bridge and the back of the tenor section
of the treble bridge?

I'm not sure about 6 or 7 seconds, maybe
Del could shed some light, but certainly some
improvement might be possible.
