The sharps and naturals will no longer have their original realtionship.</DIV> <DIV>My question to you all is, 'Am I getting into deep water with the action geometry by doing this, and am I likely to end up with a peculiar feel in the general touch?'</DIV> <DIV> </DIV> <DIV>ric</DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV></FONT></BODY></HTML>
