<div> 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: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> 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.</blockquote> What do you folks suspect, given this description? What else should I ask to get a better premonition?   Thanks in advance Jason -- =cell 425 830 1561= </div>
