I picked up an LP2 a year or so back that had a non-factory nut on it. Black in color and handsomely set. The strings rode over it quite proudly. I haven't had a "bad" nut yet but the strings do stick sometimes in a plastic nut. I went with a bone nut once and wasn't pleased with the cost or craftsmanship. I've heard about pre cut replacements that are sized to specific guitars. Supposedly they drop right in. What has been your experience with this task? Does anyone have a proven part number? With my electronics upgrade finished, I still have a little cash left and I could give my Studio a bow tie!
