String buzz

[Ed Sutton]

Jeff-
I'm guessing it is the very tip of the lever that touches the string.  Given
the mechanical advantage, you won't need to remove very much.  Slip a piece
of carbon paper between the strings and action, and pound the E.  It will
probably leave a mark on the lever showing where it touches.
