I have a local friend who is getting back into playing guitar.
He just bought a beautiful '76 Guild acoustic six string for $650. I played it. Very nice.
He bought on ebay the 12 string version of it (from a pawn shop) for $550.
When it arrived it was a Spector Euro LX series bass instead.
They told him to send it back. He said; "That's not the way it works. Send me the guitar I ordered and then send me a free return ship order and you'll get the bass. You have 15 days."
What would you have done?
