Kevin, Thanks for the ideas, I especially like your remedy for "oinking" dampers. My own piano does this (it's old and crusty), now I have something else to try. Thanks again, Stacy. > > Buzzing Dampers......... Usually caused by the felt hanging down >between >the strings too far. You really have to trim them.

Then you might have to do some minor fitting.
