Neck, 12 inch radius Maple 24 3/4. If you are building your own guitar this might be the neck for you. Made in Japan so you know its good. I bought this neck at a guitar show a while back from the Allparts booth and simply never used it. It has a square heel and could either be bolted on or glued in. Will not fit a regular Strat or Tele body because of the shorter scale. Great for a builder project. The truss rod is on the headstock end. You can check Allparts listings for other details, if it is still available. I know the owner sold out a couple of years ago and Im not sure what they carry any more at this point in time.
