I thought the same thing as well, then i figured it was the look of someone who just crapped their pants from the sheer excitement of getting a dream guitar.
someone will have to love Steve Vai's signature a whole lot to invest that much coin. Personally, I would buy it for about $500.00 with the signature. Maybe more without it...
That is a helluva arsenal... Congrats man, glad to hear the guits are working well! The Cali Custom I sold you is a very fun guitar to play live, the guys in my band told me it was their favorite of my guitars...lol
