Like an electric guitar not plugged in. I was able to move the bridge around on it's apron a little confirming a bad glue joint. After loosening the strings the bridge came off in my hands, not a drop of glue was ever applied to the joint. After gluing and screwing everything was fine. The piano must have sounded like that from the time it was new. Fenton Fenton, Good repair, but I respectfully disagree with your conclusion. The bridge was glued from day one, but failed over time. The bridge assembly is glued up before installation on the soundboard. That gritty -- dusty residue was the remains of the aforementioned glue. We see this often here in the Northeast with our extreme interior humidity swings. FWIW, Tom Driscoll No virus found in this outgoing message. Checked by AVG.
