"The damper" of the note with the noise is removed, you say? Often the bass string is making contact with the wire of the damper of the next note...

But even with the damper removed I hear it.  I suspect it is the bass string touching the treble aliquot bar below it, meaning perhaps the aliquot bar is in the wrong spot, too far up the slope of the plate. Before I do anything like move the aliquot bar, I want to run this by everyone. Do you agree this could be it?
