Yes, there are 2 different versions of the SLS. The original line had a single skull inlay at the 12th fret. All SLS made 2013 and later will have the dot inlays instead. For some reason, Schecter has not updated their website images.
I ordered and received a Blackjack SLS C-8 two months ago, and it has the new dot inlays. Im pretty sure they have stopped making the skull inlay version.
