[pianotech] More Info: The buzz that comes and goes...

[Gerald Groot]

It could be so many things.  I've had buzzes from loose or stripped lid
hinge screws on these grand's along with loose pedal lyre braces and buzzing
locks.  It could just as easily be a paper clip laying on the sounding board
too for that matters among plenty of other possibilities.

MORE INFO:  The piano is a Kawai GM-10K (5' 0").  And yes, I told the owner
to not touch a thing.  Supposedly w/ no outside changes it buzzed last
night, but nothing when the same student played it this morning (and the
rest of today).  Some of the student's music is Scott Joplin.

 

Thanks for your help, Bill

I have a customer who's 1+ year old Baby Grand has a buzz.. particularly at
3-4 keys around G5.  But when I was sent out on a warranty call the buzz was
gone.  I went thru a Pitch Raise and Tuning (since it needed it), and
"nothing".  It sounded lovely.

 

A couple of weeks later the buzz is back, supposedly along w/ a pedal noise.
Confirming the next day's appointment last night the noise was there.  I
called this morning before I left, and the noise is gone again (so I didn't
go).

 

The customer is over an hour's drive into rural America, so they agreed to
wait til the noise returns.  They have an upcoming "recording", when of
course they don't want to hear the buzz, so they are nervous.

 

Any ideas??

Thanks, Bill Fritz, St Louis
