The smaller diameter yeilds a different a localized different tension which yeilds a secondary set of partials.  I've not heard that a change in wire size alone would affect false beating one way or the other... but it wouldnt suprise me that this too would end up happening or not on a random basis. <BR> <BLOCKQUOTE>Alan writes:<BR>"Does a loose bridge pin create changes in tension or changes in the speaking length of the string?"<BR>Farrell replies<BR>I certainly don't know for sure, but I've wondered the same thing and made the assumption that both these things are likely culprits.<BR><BR></BLOCKQUOTE>Thats the going theory... sideways micro wobble allowed by both a loose pin in combination with a crushed notch edge that leaves the edge drop off behind the string.  Only problem is that there is no occurrance of false beats  in all to many instances.<BR><BR> <BLOCKQUOTE>Terry Farrell<BR><BR></BLOCKQUOTE>Cheers <BR>RicB<BR></BLOCKQUOTE></BODY></HTML>
