[CAUT] Agraffes and dampers

[Ed Sutton]

Joe-

1) Now you know what happens if you bring up your #1 question on CAUT.

2) Did someone tap the strings with a screwdriver? Look for dents or nicks.
    Just one gauge of wire? Perhaps the wire was not annealed after drawing.
    Sign of corrosion? Chemical or due to electron flow between two metals?
    When do they break? Tuning? Playing? All at once or intermittantly?
