I did not think to mass load the bridge to lower the driven resonant frequency. Perhaps that would have made a difference. The original pins coming out of the bridge were very tight. The beating was at times very fast, especially up near D7 and higher. <o:p></o:p></p> </div> <div> <p class=MsoNormal style='margin-left:.5in'> <o:p></o:p></p> </div> <div> <p class=MsoNormal style='margin-left:.5in'>The front duplex is movable on the more recent ones but if you shorten them it tends to reduce the angle from the capo to the aliquot (because that part of the plate angles downward). Nevertheless, de-tuning them does take a lot of noise out of that area. I have had one customer that pointed out an "unfocussed" sound on every note where the front duplex was longest.<o:p></o:p></p> </div> <div> <p class=MsoNormal style='margin-left:.5in'> <o:p></o:p></p> </div> <div> <p class=MsoNormal style='margin-left:.5in'> Any ideas on what else can be done for the false beating? <o:p></o:p></p> </div> <div> <p class=MsoNormal style='margin-left:.5in'> <o:p></o:p></p> </div> <div> <p class=MsoNormal style='margin-left:.5in'>Scott Nelson, RPT<br> <br> <b><i>Don <pianotuna@yahoo.com></i></b> wrote:<o:p></o:p></p> </div> <blockquote style='border:none;border-left:solid #1010FF 1.5pt;padding:0in 0in 0in 4.0pt; margin-left:3.75pt;margin-top:5.0pt;margin-bottom:5.0pt'> <p class=MsoNormal style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom: 12.0pt;margin-left:.5in'>Hi all,<br> <br> Back from my trip into the wilds of Saskatchewan to tune an Estonia 6'3"<br> grand.
