I know it is not the bridge pins because there are no bridge pins. Another form of clamping the strings to the bridge is being used.

A false beat is two different frequencies produced by the same string. To have two frequencies produced can only be caused by changes in either the speaking length or a change in the tension of the string. What is the actual mechanical link between a loose bridge pin and either of the above causes? Does a loose bridge pin create changes in tension or changes in the speaking length of the string?</FONT></STRONG></DIV> <DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV> <DIV><STRONG><FONT face=Arial size=2>AF</FONT></STRONG></DIV></BLOCKQUOTE></BODY></HTML>
