Hi there, I have a Clover anglo and the primary "C" button on the right hand (pointer finger) valve pad seems loose, or the button is wobbling, or something shifted. It keeps resulting in the valve pad resting slightly on top of the valve pad below it, which lets air through and the note keeps sounding even when the button isn't pressed.
Any thoughts on what could be loose, worn, or going surprisingly wobbly here? I do play a fair amount, and this would be one of the most used buttons.
Thanks,
Geoff
