Hi, Dave, Make a tool from a 3/16 piece of brass or steel and cut a notch in the end, rounding the endges and put a bend in it or put a handle on it. The tool needs to be about four inches long (not including bend or handle) and the notch about 3/16" deep. Massage the string down at the bridge so all strings conform to the bridge evenly. If the partials still do not coinside use the tools to enhance conformity to the bridge pins by twist the tools left and right until something happens. You might also check how the strings enter the agraffe. This little tool is a wonder at reducing falce beats in the treble. The tools is the envention of John Hartman.
