Thanks to all the many and varied posts regarding ways to limit the sound production of a grand. It was interesting to me how many different approaches are used. Also interesting was Ron's point that muffler rails seem to be absent from this list of cures. While common on uprights, I have only seen them on non-verticals on the three square grands I service. All three are operated by a hand lever. Seems to have been standard equipment back then... Mark Potter bases-loaded@juno.com
