[pianotech] Noise from strings after sustain pedal is depressed

[Richard Brekne]

Be very careful Renee. You need a very sharp pair of scissors and you 
need to do very accurate clips. The idea is that the wedge felt is 
sticking too far through the strings.... but it needs to sit at least 
barely through and very evenly so. If you get it wrong you wind up with 
a string that doesn't damp.... and you need to replace the felt.

Another thing... this job really requires good knowledge and skill in 
re-regulating dampers. You can not access the dampers well enough from 
below unless you have a special pair of scissors... also very sharp, and 
are routined at it.  Myself I gave up on that idea years ago and simply 
remove them one at a time and clip them using the string marks as guides.

This is an easy job to get into trouble with.

    way around it as its in a studio.
