Jason, 

Something that made my ears "perk up" was the comment about "off-color" side tone. Besides the obvious things you'll check, I'd also check the string level/hammer mating thing. A bad one can cause a lot of "off-color" tones! :-) Besides, it's a Baldwin! :-D Of course, it might also be an agraffe noise.

Group -
I have been asked to travel a couple of hours to fix a mystery noise. To save time I asked the owner for as complete a description as possible. Here's the response:



I have a Baldwin grand that has had a buzzing key since I

bought it about a year ago...

It's the B right below middle C. Been there since new.  I'ts not a

buzzing exactly, but an "off-color" side tone.  The other tuner has 

worked on it 4 or 5 times, and replaced the string, with no help. Of

interest is the fact that I can also hear it on adjacent keys (but to

a MUCH lesser extent, almost inaudible).  I can't find anything loose 

that might be vibrating.  It's such a commonly used key that it's

quite annoying. I notice it even when playing chords.


What do you folks suspect, given this description? What else should I ask to get a better premonition?

 

Thanks in advance

Jason
