Our JZRO-MOD replacement neck for Jazzmaster is officially licensed by Fender and made to exacting quality standards in Japan. Based on our best-selling JZRO neck this "MOD" version offers truss rod adjustment at the headstock rather than at the neck heel. With a modern 9.5" radius and tall narrow frets our JZRO-MOD offers easier string bending and precise intonation. And with truss rod adjustment at headstock seasonal adjustments will be easier than ever.Unfinished and ready to spray you can finish our JZRO-MOD any way youd like
