noisy dampers

[Carol Beigel]

Don't bother disassembling the piano!  I wouldn't trim those damper felts 
either.  Do:

1) try sticking a single needle in the damper felts to "voice" them

2) tell the customer that the piano is "breaking in" and that when the 
damper felts get grooves in them they won't be so noisy

I think any brand new grand piano today makes the "swoosh" sound when you 
tromp on the damper pedal!
