Please see pictures for details This is a Mexican classic series neck. From about 3 F to 20 F, the 1 3 string side is scalloped. Nut : 42.0mm 1F : 21.2mm 12F : 23.4mm End Width : 55.9mm Weight : 688g Neck : Flat Fret : 100% Rod: I’ve made sure it goes half way around in the tightening direction. Beyond that, we are not sure considering the burden. The nut has been replaced with a metal one. The paint has come off on the upper back of the head. The frets, rods, and warpage seem to be good, but since it has scallops, consider it as half junk. 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.
