Hello everyone.  I=92m new on this list.  Hopefully some of you can =
offer some
advice about this=85I=92ve only been tuning for about 2 =BD years and =
I=92m trying
to learn to do small repairs as I come across them.  This is something I
don=92t know how to fix, and I=92d rather ask than cause damage by =
trying
something that might be bad for the piano.

A piano I tuned today is buzzing around the middle of the soundboard in =
the
bass section.  It buzzes loudest when I play C#3 and buzzes a little on =
a
couple of other notes.  I looked and can=92t find any cracks in the
soundboard, but it sounds like wood on wood.  The buzz stops completely =
when
I apply pressure to the top of the soundboard and also if I push up on =
the
ribs in that area.  The client just bought this piano brand new about =
three
weeks ago.  The brand is River.  It=92s under warranty, and I=92m =
wondering
whether he should just send it back and get another one.

I felt bad having to tell the client that his brand new piano is =
buzzing,
and I wish there was something I could do to fix it.  Would some sort of
really thin shims work?  How about just trying to get some glue above =
the
ribs in that area?  Any advice you can give me would be appreciated.

Take care,

Brandon Robertson
