Hello all. I just installed a set of flatwounds (1.05-0.40) and whenever I hit open A, the string pops off of the nut! I think that since there is only one revolution around the tuning head, it is placed up a little higher than the other strings. What should I do? First thought would be to file the nut down so that it sat farther down in there, but knowing me there is probably an easier way.
