Dear List, I have a client with a problem Mason & Hamlin BB. The piano has a very strong harmonic produced by G#5. The sound continues after the key is released and cannot be stopped by blocking the string or any related strings. The sound is also produced, but to a lesser degree, by G#2,3, &4 and by C#3 & 4. I have tried blocking all G# & C# strings in the piano as well as muting the strings behind the bridges to no avail. Any advice would be greatly appreciated. Thanks, Dan Rue, RPT
