Buzzing Acrosonic

[Ron Nossaman]

Hi Mike,

If she cleans the top of the piano off for you before you arrive, that's
where to look first. Next time, call just before going out to verify that
the buzz is still there and make her SWEAR not to touch ANYTHING until you
get there.

If that's not it, thump on case parts and listen. Check the long fallboard
hinge pin, pedal rod bushings, etc. You know the drill. Also, fist-thump the
floor and the wall behind the piano. I once found a buzz in the bathroom
heating duct in the wall behind the piano. Went down in the basement and
wedged a piece of cardboard between the duct and joist to save the day. I
wouldn't have a REAL job for anything. Wanna buy a duct?
