Question if anyone has experience: Earvana is now making a drop-in nut for Gibson style installations which has a little shelf instead of the screw-in head (thereby nixing the requirement to cut off some fingerboard for a solid Earvana nut- they cut the nut instead.) They do NOT, however tell us anywhere on the website what the radius is (the ESP version is 12"-13"). I assume for a warmoth compound radius tiltback head neck we'd want a 10" radius, correct? Anybody put one of these on or at least know the radius? ???
