Just got a second one. Used the first on a Tele build. The multiple heights included give plenty of options. Takes some tweaking but so does a standard nut and you don't have to worry about overdoing anything.
Works as described but installation was a pain. I have a warmoth tele neck that I installed it to. I had to cut back the nut slot a little to fit the new bone nut and fret in place. I thought it would just drop in.. I wasn't anticipating that but my skills didn't let me down. I filed the nut and fret down on both sides a little, added some super glue and now it works great. i have a bigsby so tunning is a breeze now!
