This is a 2011 Limited Edition Closet Classic 58 P Bass.  This is #8 of a total of 15 made  - so a very rare piece.  In excellent condition, but it does have a minor indent on the back of the neck and some minor impression from the tins having been mounted over the bridge (see photos).

This bass features:
 Double contoured hand selected ash body
 Nitro finish in White Blond
 Quartersawn Maple neck with a soft V shape and 7.25 radius.
 Custom Shop Split single coil 58 P Bass Pickup
 Limited Edition Hardshell Case

Ships with OHSC, Certificates of Authenticity, tins and strap.  Bass will be professionally packed prior to shipment with insurance and tracking.  I've included a copy of the information available on the Custom Shop's discontinued models page - from the grain pattern I believe this bass to be the one in the CS ad.
