List,
I service a 10 yr old Boston UP132 that has seasonal buzzing issues throughout the tenor and treble sections. I was at the piano 2 weeks ago, and heard nothing, and now my client has told me the buzzing is unbearable. A couple of years ago it was present while tuning, and I inspected everything I could imagine. The ribs and SB assembly seemed fine (though the current buzzing is very much like a SB/rib buzzing). The only thing I could do to lessen the buzzing was to press against the bridge with a screwdriver where I could reach it, and indeed the buzzing diminished. This definitely made me suspect the joint between bridge/SB.
My question is- how could I verify that this may be what’s causing the buzzing, and what potential fixes might I offer? I have seen on this list suggestions for applying CA to the bridge root/SB joint, but have not had the opportunity to try this.
Thanks for any tips.
