You are looking at a nice Jackson compound radius guitar neck (loaded).  This neck was removed from an Adrian Smith SDX guitar and is less than 6-months old.  Dead straight with zero fret wear.  See specs below:

*  12 - 16 radius

*  Fast / Thin U Profile (not as thin as Ibanez)

*  Laurel Fretboard

*  R3 Locking nut (black)

*  String Guide (black)

*  Inline 6 tuners (black)

*  XL Jumbo Frets

*  Bottom Truss Rod

*  2 1/4" Butt (for Jackson / Charvel / EVH / etc. Bodies)

*  Jackson Neck Plate included

*  Original Neck Plate Screws included (very important - stripping)

Cost breakdown:

* nut ($30)

* tuners ($30)

* string guide ($10)

* neck plate / screws ($30)

* compound radius neck ($185)

Final Thought:  This is a great neck comparative to other top Fender products (Jackson / Charvel / EVH / etc.)  for less and in almost new condition.  You won't find this neck in this condition very often much less at this price point.

FYI, I am going to replace neck with one built with medium / medium frets (my preference).

Thanks.
