When I muffled every darned back length, I did find that the offending note still stuck out. I think that muffling too many back lengths can add to the problem, since it quiets down so much of the after ring of the other notes, which makes the loud one stand out all the more. The trick is to find out what is reinforcing _only_ the loud note. When you muffled the waste lengths, did you get _all_ the long tenor ends, even the parts hiding under the plate, so that when you plucked them they sounded dull? Sometimes one noisy one is lurking down there ... If you do manage to quiet down the offender, then the trick will be to remove as much of your muffling as possible, without it starting up again. You don't want anything muffled which you don't NEED to stop that one note. Good luck ... let us know if you work something out. Susan </html>
