I tightened every screw I could find, hinges, cabinet, lyre, plate bolts. I checked the bridge pins to see that they were fully seated in the bridge.</DIV> <DIV>The only way I could eliminate it was to lay under it and press up on 2 ribs above the beam (that extends to the nose) about 2/3 of the way toward the bass bridge, approximately under the tenor bridge.</DIV> <DIV>I also cleaned under the plate and bridges looking for forign objects.</DIV> <DIV> </DIV> <DIV>Now what? The concert is tomorrow night.</DIV> <DIV> </DIV> <DIV>I would appreciate any advice,</DIV> <DIV>Mike<BR clear=all><BR>-- <BR>I feel sorry for the person who can't get genuinely excited about his work.
