The ESP Guitar Company

First post here....woohoooo!!!! I just got a used KH-602 w/ serial number W08XXXXX for 600 bucks delivered off of ebay...... thought it was too good to be true, but when it arrived it was in the original ESP box it came in and the serial numbers matched up between the box and the guitar, MINT condition (just as advertised), not a single scratch, great neck....the axe is beautiful and looks like a 100% legit LTD....only thing that made me suspicious is that the headstock is missing the KH signature. I looked all over the web and even got my hands on the older ESP catalogues, and all the KH-602s I could find had the signature on the headstock. The only ones without were the older models (which still used the ESP truss-rod cover) and the 202's....but this is definitely a neck-through so it cant be a 202 and the serial number indicates made in 2008....so whats going on?!!! Is it legit or not?!!! Thanx dudes! NJ
