Hi John, Before you go trying strange stuff with this damper get some Silly Putty and stretch out enough to cover the aliquots from where the stringing braid ends all the way to the top. Check carefully that the stringing braid is indeed effectively muting the waste ends of the bass strings and the middle section _including under the bass strings_. This is to eliminate any possibility that you are getting sympathics from any other source. It is a waste of time to futz with F2 if the source is else where. Newton
