Please see pictures for details Nut : 42.1mm 1F : 20.5mm 12F : 22.5mm End Width : 55.5mm Weight : 415g Neck : Flat Fret : 60-70% Rod: I checked that it goes around 1/4 in the tightening direction. Beyond that, we are not sure considering the burden. Unusually for Fender Japan, this neck is thin, light, and has a USA standard end width. It may be G-serial, but there are many guitar with special specifications in this G-serial period. 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.
