Ok, so I bought an S2 from a guy off of Ebay (yeah I know!) Anyways the guitar came in and the SN does not have an "S" before the 2 in the SN. I contacted him and he said that he is an endorsed artist and got the guitar before they were public and it was more of a prototype. I checked for all of the tell tell markings of a PRS and they are all their. The SN in the treble pickup cavity on the sticker matches the headstock. Also the pups in it are some type of American PRS pickups and not the G&B (I have a separate thread asking for info on the pups). Any info?
