Only the loud buzz was intermittent. I did everything I could think of (all the screws everywhere are nice and tight now!) and it would seem to go away, only to return at a later date and drive the pianists crazy. Then it would "magically" go away again. It happened immediately after trying some new procedures on it with a visiting tech and Murray kept insisting "It's his fault! We never had that problem before." Finally, the night before a two piano concert, the noise was back and _bad_. I was desperate, I had already tried everything I could think of. So I started trying them all again. Lo and behold! A small, round thingee wedged between the plate and the soundboard in the high treble where it could barely be seen with a flashlight and mirror. When it was humid, it was tight, when the board dried out, it buzzed. Even after I found it, it took a long time to get it out. It was the knob from a microphone. Now it's my trophy :-) Diane _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com
