I tried it on my Charvel Demartini snakeskin-unfortunately Charvel drills their Floyd nuts with different spacing than usual so check that first. Otherwise I would have kept it, the open chords sound much better on my guitar that has it.
Oh hell no. Are they high? Is that a typo? Did they mean $14.95? I'm shocked this actually finally came out. It's been listed as "coming soon" on their website for at least 5 years. Cut a tiny sliver piece off of a Teflon guitar nut, glue it to the front of your FR nut, in front of the G string slot and voila! Problem solved for 2 cents.
