I've got an old 65 and all the keys have a lot of movement, and all of them sounds when been shaked so it seems that instead of a calc I have a maracas.
The think is, as I post before, the 4 in my 42s have a curious click when is softly pressed so I wonder if is the same problem and if somebody have any experience about this subject.
Have the 42s keys a spring between the bubble and the plastic and can it justify the sound?
Thanks
