If the nut height is too much, there is 2 solutions. One is making nut string slot deeper till strings set on S.O.S. In this case, if you take out S.O.S, the string height will be lower and may have buzzing. So we reccomend to test with spacer tape (0.1mm thickness x 3pcs, included) and make S.O.S height higher and after checking S.O.S works well, you adjust the nut slot deeper.
If you want to keep the original nut condition, you should make S.O.S height higher than nut slot.
Please use the spacer tape and adjust S.O.S height. If the height is not enough, we advise you to use thin plastic sheet and glue to S.O.S to make suitable height. But Nut side height will be higher than S.O.S target, S.O.S pitch improvement will be less.
