I think Ed's suggestion is an excellent one, based on experience. I think the reason it works is because the level and mating weren't quite perfect. <DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>I also move the string back and forth, if this doesn't work, based on the notion of tiny metal shavings on the capo causing the noise. I move the string back and forth using a prying method: screwdriver blade inserted between capo and string from the duplex side, grabbing the string with the corner of the screwdriver blade, twist the blade so that the other corner of the blade is bearing against the capo, and ease the string over. You are prying downward, relieving pressure on the capo from the string, so that you don't "plane up" more metal shavings.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>Check if it is at the bridge pin, by bearing a screwdriver blade on the pin while playing the note, and also on the offending string itself ahead of the pin. What to do "on-site" while tuning if this is the problem? If the pin is loose enough, try rotating it a bit, so the possible shaving on the pin is away from the string. Dose the base of the pin with thin CA. </DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>And, of course, the already mentioned lower tension and pull it up on the other tuning pin, to move the string itself through the bearing points. And then address both strings at the bearing points to re-create positive bends, for tuning stability, tone, and to level the strings again.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>In the interest of avoiding such noises and what I have found to be the causes of them, I like to space my strings pretty carefully before bringing them all the way to pitch. Do it with the strings taut, but so that you can move them pretty much with a strong fingernail. Any final spacing touchup is done as above. On pianos where I have re-strung the capo sections, with new bridge pins, dressing the capo, and the above string spacing method, and with good string leveling and hammer mating (with travel and square understood), I am not plagued at all by objectionable front duplex noise. </DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>Now I confess I haven't tried this on a Young Chang PG-213 (more or less Steinway B copy), which has the nastiest front duplex noise problem I have ever heard. I've seen a few of these, all with the entire front duplex completely muted. Decided to see what it sounded like with mute out one day. Wow! But, then again, I haven't done any of the meticulous prep work on it, so maybe it can be made not so bad.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>Regards,</DIV><DIV>Fred Sturm</DIV><DIV>University of New Mexico</DIV><DIV><A href="mailto:fssturm@unm.edu">fssturm@unm.edu</A></DIV><DIV><BR class="khtml-block-placeholder"></DIV></SPAN></SPAN></DIV><DIV><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV> <BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">OK guys,</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">This is mostly something that should be looked at and taken care of with</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">restringing.
