Damper "shooshing" noise

[FSSturm@aol.com]

Never discount the possibility that the customer may be describing a problem 
inaccurately - they know something is wrong with the dampers, and assume you 
will figure it out. It is always possible that the complaint is not for a 
noise generated during damper rise, but rather on damper return. I certainly 
hear a lot more complaints about the sound generated when the pedal is let up 
very slowly (dampers slowly coming into contact with strings), and this is 
often described in such a way that my first impulse is to look at the pedals 
and trapwork. In a case like this, where you fail to hear the porblem, it 
might be a good idea to ask to listen to a tape where the offending sound 
occurs. Then you can get a much better idea what the problem is likely to be.
    If it is noise on damper rise, I have nothing to add to what has already 
been offered.
