Soundboard Springs. Long.

Hi Del,
Server's been down (yet(yet(yet))) again, and I fished this out of the
archives just now, since it still hasn't shown up in my in box.

A couple of these maple "pads" between ribs would be in the 100 gram range
in weight too, adding not only stiffness, but considerable mass too. Seems
to me that likely had something to do with that configuration working
better. Double impedance boost.
