That device exerted pressure on one of the ribs via a backpost, thereby enhancing that dead sounding note to blend in with the rest. We christened the device with the honorable title "Anti-Node Dynamic Soundboard Adjuster" (ANDSA) :-) This reminds me of a device talked about by the late John Bloch in the May 1980 Journal in his series of articles intitled "Chips off the Old Bloch", where his idea was very similar, but instead, he used springs. vince mrykalo rpt byu provo utah ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ It is theory that decides what we believe-Einstein I believe that is a sound theory-VM ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
