Please see pictures for details Nut : 42.8mm 1F : 22.5mm 12F : 25.0mm End Width : 56.9mm Weight : 685g Neck : Flat Fret : 65-70% Rod: I’ve made sure it goes half way around in the tightening direction. Beyond that, we are not sure considering the burden. This neck is a rare 54 model in Fender Japan. I think the nut has been replaced. The operation works well. The sound output is also no problem. And the operation of each button is also comfortable. If that, please let us know within 3 days you got the item.
