mystery buzz

[Mike Kurta]

    Jason:
    I've found it helpful to have someone play the offending key while you go under the piano with a hardwood dowel and push up and pry against the soundboard in various spots.  If you find an area that changes the sound, you may be near the source.  Coming from an auto repair background, I've used a mechanic's stethescope with a probe to locate noises also.  In a pinch, a long screwdriver with the handle and against your ear might be helpful in leading you to the buzz.
