If the tone only lasts 3 to 4 seconds, what kind of piano is this that =
all other features such as strings, hammers, board, action and tuning =
are correct? Sounds like something is broke to me.

Terry Farrell

What appears inconsistent here follows: The subject piano is said to =
have good strings, good hammers, a good soundboard, a good action, and a =
good tuning - and I think it is fair to say that the suggestion here is =
that the piano is a good piano, in good shape, and nothing is wrong with =
it. My comment was meant to suggest that if the piano only has 3 to 4 =
second sustain time, that there is in fact something wrong with the =
piano - in fact it may be poorly designed, or lacks appropriate =
downbearing, has a collapsed soundboard - or perhaps it is the presence =
of the rear duplex shiny thingees that is choking the sustain?
