I serviced an Acrosonic a couple years ago that had a completely dead bass. 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.
