Floyd Rose users considering the LOK-N-Roll nut;
I bought and returned mine because it just screamed ******** but I had to try it. Check out these ridiculous claims
Increased note clarity
Even tension across the fingerboard
Reduced hand and wrist fatigue
Piano-like pronounced chords
it doesn't work. it's snake oil. have an almost impossible to find Earvana floyd nut on my axe & it works like a charm. i ordered & tried the Lok-n-roll and all i can say is it does NOT work as advertised. i have been a floyd user for almost 40yrs & am an expert user. I don't know why Ernie Ball sued earvana so they had to stop making the nuts. But they still make regular nuts which I just don't understand. All I can tell you is caveat emptor.
