Hi Tod,
So far we haven't heard any real information at all about the details of
the symptoms, so shooting in the dark with suggestions probably won't bee
all that useful. How about some specifics? I see you mentioned that the
pins weren't loose in the block. Why assume the block needs replaced then?
Are the strings rendering easily through the bearing points? What happens
when the pitch of a string is raised, and it's hit a hard blow? Does it
move (render through the bridge)? What were the immediate symptoms, in
detail, that kept your friend at one unison for 20 minutes. I don't see how
that could possibly be a pinblock fit problem. So how about some more
information?
