I was gonna guess.....from Joe Public w/ the original case you gave $2500 for it.
But...case is gone, (from the seller, but you have one) and you got it from a friend.....any rational assessment goes out the window!!!
$1800 (?) I'll guess. If you don't want to say, that's cool. I'm just interested in the pricing of the guitar. If it's none of my business, I'd understand.
