I can guess the subject is the Sounding board, that = the Plate Crowned board is that part where the bass strings have their own = off-set bridge. Or am I on the wrong side of the board entirely? By the way we = have "Levers" here where you have "Whippens" (and even the spelling of = "Whippen vs Wippen" has had an airing)</FONT></DIV> <DIV><FONT face=Arial size=2>Cheers  Michael G</FONT></DIV></BLOCKQUOTE></BODY></HTML>
