>List,

>Went to tune a Sohmer console (although the problem in question was not 
>necessarily specific to this make).  Client complained that the damper 
>pedal wasn’t working well.  Dampers were coming off the strings when 
>the pedal was fully depressed, but just barely.  I turned down the nut 
>on the threaded rod attached to the pedal to time the lift sooner.  Not 
>enough time on that visit to determine why it had gone out of 
>adjustment (assuming it had ever been IN adjustment).  Problem 
>solved….until several months later when the client called that the 
>damper pedal was again not working, making playing her piano a 
>“hateful” experience.  Well, we can’t have that, said I, so off I went 
>to get to the bottom if this problem.  Turned out to be something I 
>hadn’t seen before.  Can you guess what it was?

>Cheers,
