Joseph, others have mentioned the let-off rail..that's too easy.. How about this: I'm betting that nothing has changed in the let-off of the affected area, but, the piano has been moved..it also sounds like you're seeing this piano for the first time..I'm thinking (stop it Driscoll..you have no room to talk, and I've been nice) that the new position of the piano has caused the owner's ears to hear some different that was actually the same before the piano was moved. Was the piano on a hard surface before the move, and now it's on carpeting? It sounds like the let-off hasn't gone berserk..it was there before the move.. Nothing else in a console piano besides a loose let-off rail can affect that adjustment that much without affecting more than just one area. It hasn't changed..only the position of the piano. Just my $.02, -Phil Bondi(Fl)
