If that makes any sense at all. Or possibly it sounds like a little mini golf pencil in exactly the wrong spot on the key where it can bounce off the capstan but not hit its neighbors. It appears on F#3 and a little on F3 and A3, nowhere else. I have repinned, reglued hammer heads, tightened screws until I'm blue in the face, even checked leg bolt washers, damper and sostenuto screws and key leads. Any ideas no matter how bizarre or obvious would be appreciated. -- ----Dave </BLOCKQUOTE> Dave, Another possible source would be lyre brace screws, though Yamahas are p= retty secure in that department.  I've had the phillilps head screws co= me loose and cause a heinous rattle that sounded like the soundboard was dis= integrating.
