[CAUT] Bass string & Aliquot bar contact noise

[johnparham at piano88.com]

Don't forget to check the agraffe.  Is it perpendicular to the strings?

Look at the front duplex in the "hidden area" where the string makes its
bend under the capo bar.  There is just enough room for a small object
to fall down there and never be noticed.

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?
