Baldwin L Buzz

[Farrell]

Buzzing in low tenor bridge area. Bad buzz. Buzzez on most notes, some more
than others. I've always been able to find the cause of buzzez on other
pianos before. This one is a 1940s Balwin L. I have pressed on every area of
bridges, every rib, every plate thingee, every hinge, etc. (while owner
strikes buzz-making keys) and no significant effect on buzz. The only thing
I can imagine is a penny or paper clip or some such object on the sounboard
under the plate where I can't see it. I told her next time I will bring my
tank of compress air and we will make clouds in her living room.

This is a dirty dusty piano. I would rather try another technique if
possible. Am I neglecting to look for something else? Is there some great
buzz-finding technique that I am not aware of? Is there some way to
thoroughly search the under-plate area (each time I tune this piano we spend
a half-hour looking for this buzz - and I have swept as good under there as
possible with my trusty Bill Spurlock soundboard cleaning tools - but I
can't get everywhere)?

Should I tip the piano up on its side? Maybe whack away on the bottom of the
soundboard with a sledge hammer? I feel like I'm getting a bit manic with
this one - I don't want it to win! Help!
