The ESP Guitar Company

Going to put this up for sale soon and I want to give any potential buyer the most accurate info possible. I bought this new around 90ish, maybe 91?  Anyone remember when the Screamin' Demon was released?  Because, when I took delivery of this guitar, I was pissed it didn't come with an sh-6 and the demon wasn't even available for retail yet.  Six digit serial, non recessed Floyd, grey pilot, zebra demon
