Hello everyone, Randy, have you ever tried reaching your hand up from underneath the piano to where the soundboard is glued to the rim and felt to see if there was any hard thin pieces of glue that squeezed out when the piano was built? It may or may not have anything to do with the bridge but it is worth a shot. I've seen this problem on a brand new quality piano as well. Doug Hershberger, RPT
