All but two of the keys have EXTREME side-to-side wiggle, and I’m assuming this isn’t typical. I haven’t been able to recover much info online. I’m refraining from opening this baby up to peek around, as I don’t want to make matters worse. Right now, I have the option to send her back, but if there’s an easy (read: cheap) fix, I don’t mind doing some work. Could there be bushings in there that have just fallen apart? I do hear some pieces rattling around inside. Thanks for the help, all.
