[CAUT] Baldwin SD

with it, I've once or twice (making sure that no one was looking) taken a
small blunt screwdriver, placed it between the strings on the non-speaking
side of the agraffe, and twisted sideways. It felt like a somewhat dirty
procedure, but the noises stopped."

Susan, was it necessary to tune the affected strings right away?? I am 
wondering if you exerted sufficient force with the screwdriver to move the 
wire on the other side of the agraffe. That is to suggest that there was 
some issue further down the wire that was resolved. Hmmmmmm............
