From Fender:
Crafted at our Ensenada, Mexico, manufacturing facility, this genuine Fender Baritone Sub-Sonic Stratocaster guitar neck will convert your standard scale length guitar into a 27.5” scale length baritone! Features a comfortable “modern C” profile and 9.5″-radius maple fingerboard with 22 medium jumbo frets.
The nut is pre-slotted with “pilot” string location grooves to make spacing a breeze when performing the final string slot filing, and a satin finish on the back offers smooth playability.
This replacement neck is for a Fender or Squier by Fender guitar.
