I recently was called to tune a 10 year old Steinway "L". Although the piano is in excellent shape otherwise, it does have a very loud "thump" at the end of the pedal release.Damping is fine, trapwork regulation is fine as well. The felts are pristeen, although when I return I am going to spend some time trying to soften the felt a little to see if that helps. The thump is definitly being caused by all the dampers seating at precisely the same instant.(both front and rear). Shouldn't the dampers lift just slightly tilted front to back(back side lifting first)? The owner says that this thump has always been there.Of course, any grand damper set will make noise on a rapid release of the pedal but this is REALLY loud. To make matters worse, the piano is in a large open room, hardwood floors, NO furniture or drapes and 12 foot ceilings. Any thoughts,tips, suggestions? Paul E.
