Dear Ed, If you have been through this piano VERY carefully eliminating the obvious areas of the suspect buzz then I would look to the bridge area. Even though you may not be able to get a very thin metal shim between the bridges and soundboard, there may still be a gap that one simply cannot see or feel by prying. Carefully apply a water thin solution of CA glue at the base of the bridge and let it seek any gap (**let it air cure...don't accelerate**) Air curing will allow it time to seek as far as it will and also keep from forming the nasty looking white crystaline pockets . Start with the area nearest the problem buzz and work your way out. Hope this helps......lemme know how it goes! Regards, Dale
