I've had a few pianos where one (or another) note around the sixth octave would ring on too long and too loud. I tried plucking all the different waste lengths (especially the ones behind the bridges) that I could. Sometimes it seems like a bunch of them are reinforcing (mainly) just one note. Keybushing cloth cut into strips makes effective stringing braid, but one has to decide just how much to use. Our SD-10 had the problem, which got me very frustrated, and I tightly braided a whole lot of the waste lengths from the middle treble right down to the end of the tenor. It was muffled up to its eyeballs, and the after-ring (the normal after-ring) of the whole instrument was really crummy and dull. I took it all back out again, and just used a little bit of extra braiding on the super-long tenor strings. They can have the original braid, and still have too much sympathetic resonance, because the waste lengths are so long, where they go past that round plate opening. Sometimes just a little fold or two, hidden under the edge of the plate down at the tail end, will be enough. If you have a helper, you can have him or her keep playing E6 while you wander around the tail end, muffling this or that place to see what you get. Why would it suddenly get worse? --- The original braid might have suddenly worked loose; or the problem gradually appeared, but nobody paid attention till it became really obvious.
