I bought this to convert my right handed Fender Standard Telecaster to left handed orientation for my wife. Popped out the old nut fairly easily. Filed down the tab at the bottom of the new nut, as it wasn’t needed for the neck I had. Quick file of the edge of the nut as it was a hair longer than the original. Stringed the guitar back up (backwards), adjusted the bridge saddles and hey presto, she has a lefty guitar to jam on. The tusq nut is good quality with a pleasing sound when you drop it down on something, unlike the dull thud from the stock nut. I bought a right handed one too at the same time, just in case I ever want to reclaim the guitar back for me.
