An additional note. The Serial number S0551103. Here is how ESP serial number system goes. The first first letter(s) designates the Custom Shop, Original Series, Signature Series, Standard Series etc. For the Custom Shop and Original Series models you'll have:
K, S or T. S = Sado.
So this guitar is made in Sado Island Custom Shop. I can send picture of the serial number behind the headstock if anyone is interested.
I'll say this is a damn good price for an ESP built in their Custom Shop.
