Sounds like it may have been a quick solution to a buzz that was very difficult to find. By putting pressure on the soundboard, the buzz went away, so someone put "permanent" pressure on the the board from underneath. No telling where the buzz (if any) was coming from but this might have stopped it. Just a guess... Reminds me of the old German piano maker's "Pfennig Trick." A long screw was put completely through the case beam (upright or grand) and the point of the screw pushed up on a Pfennig (penny) which pushed the board up to "add" crown to a tired, old board. But that is another subject! ----Joel Guy Nichols wrote: > > On TOP of the central belly beam, directly under the tenor bridge, about > where notes 36 thru 40 cross the bridge, is a collection of hardware that > just doesn't look like factory installation.
