<html> Hi Z!,          The bridge is secured with dowels that go through the ribs, board, and bridge.  Each rib has a dowel if you look closely.  The bridge of coarse, is glued through out the length.      Check the bearing through out the problem area, and the crown.  Use an artist pallet knife to probe the rib security, ( .010" thick). Also check the glue joint around the perimeter of the board, not forgetting the belly rail from inside the action cavity.  I have found a few buzzes, by pressing down on the board, (with a blunt screw driver) along the belly joint.  In the high treble the joint is only about 3/8" deep at the belly rail. Search for any items like paper clips, that may have been dropped under the plate.These type of buzzes are often hair pullers. Good luck and have fun.

The problem:  A buzz -- that nasty wood-on-wood sound similar to the loose-rib sound Found so far:  Light pressure on the bridge over the affected area will make it go away.  The affected area is near the treble break, right about where the strings to note G6 cross the bridge.  The buzz is activated by notes C4 (middle C) and to some degree C3.   (Or am I dealing with a loose rib or a failed glue joint between the rib and the board?  I didn't see any cracks in any glue joints around the ribs.)   Is there a suitable in-home repair?  My temptation is to install some strategically placed screws, but I'm hoping that others on this list have better ideas.   Thanks in advance -- Z!
