I own one, it has a thin neck from front to back(19 MM at the first fret and 21 at the 12th) and a 1-11/16ths nut size, the inlays are mother of toilet seat(plastic)
the trem is OK but i replaced it with a OFR from
www.warmoth.com
the pickups are also OK but were replaced with a duncan TB 5 custom and a lil 59 in the neck and a classic stack in the middle.
now after these mods the axe is a killer.
i paid $200 for it used and put in another couple $$$ and got a great pro axe!
