I want to thank all those who generously responded. </DIV> <DIV> </DIV> <DIV>Some people asked me to be a little more specific about the = problem, so here goes.</DIV> <DIV> </DIV> <DIV>The problem is most prominent in the bass bi-chords, = although it shows up in the singles as well. High overtones are quite audible in = single strings of the bi-chord, ie. I've muted off one string. The overtone is = not coming from the back-string area, nor is it coming from undampered = strings, nor is it coming from the room or any other part of the piano. The overtone = is clearly being generated from the string itself. </DIV> <DIV> </DIV> <DIV>QUESTIONS:</DIV> <DIV> </DIV> <DIV>1. Has anyone had any luck getting rid of this noise by rescaling = the offending string(s)?</DIV> <DIV>2. Has anyone had any luck by installing Scott Jones' "Pitch Lock" = string couplers?</DIV> <DIV>3. Ted Sambell was doing some experimentation, at the Banff Centre = a few years back, by adding mass at one end of the string. Has anyone else = tried this? If so, please describe what you did and what was the result.</DIV> <DIV>4. Is this just the nature of the beast, and the client is going to = have to live with it?</DIV> <DIV> </DIV> <DIV>I look forward to any suggestions and answers to my = questions.</DIV> <DIV> </DIV> <DIV>Sincere regards,</DIV> <DIV> </DIV> <DIV>Bruce Gibson<BR>Piano Technician</DIV> <DIV>Saskatoon, Canada</DIV> <DIV> </DIV> <DIV>Cell - 306.221.3786<BR>Fax - 306.955.3725<BR><A href="mailto:bruce@bgpianotech.com">bruce@bgpianotech.com</A><BR><A href="http://www.bgpianotech.com">www.bgpianotech.com</A></DIV></BODY><= /HTML>
