+ 1 Oops.... This should be "fret at the 3rd" not 2nd. Or, another excellent method is to cut the depth of each nut slot so the clearance between the bottom of each open string and the top of the first fret is roughly the thickness of each string. Make sure nut is cut after truss rod and bridge saddle height are adjusted properly. No nut cutting in this case as it is a Floyd locking nut but thanks all the same! It's the same for either type regarding the proper string height at the first fret, but I realize you're limited with the Floyd nut since you can't cut each slot.
