Noah The problem on this piano is probably not the loose let off buttons,but expanding action brackets. Weber grands were made by Young Chang. The action brackets on YC's for many years, for some strange reason, actually expanded, which threw off regulation. YC used to give you four new brackets, but I don't know if they still do that, so give Young Chang a call, and ask if they still give them out. You'll need a serial number of the piano. The customer will have to pay to have new action brackets installed. The latest information I have for Young Chang is: Parts manager at Young Chang John Chang, 866-798-6979 ext. 144 Jchang at ycapiano.com Parts manager at Young Chang John Chang, 866-798-6979 ext. 144 Jchang at ycapiano.com Jchang at ycapiano.com Monica is the receptionist at ext. 0 But I heard that John is no longer there.

This is the first time I've seen the piano, so I put a pencil mark in the center of the let-off buttons to check their possible movement when i return in 3 months. If they do move, is there a way to tighten them up, like Loctite or something? Otherwise they will have to be replaced. At least the buttons themselves, if not the metal thread. -------------- next part -------------- An HTML attachment was scrubbed...
