What an idiot kid. You can't feel bad about taking advantage of a moron. His dad would be totally ashamed of him. If I was alive and my kid did that, I'd have some words for him.
If he is a kid $200 plays much bigger and who knows he prob got the amp from another kid for a steal too...money by dollar amount doesnt give any idea of the value you get. Would you be an idiot for selling a Scruggs for $500 if you could take that $500 and get something a lot better...no you wouldnt. It was scrap wood to the kid, who clearly liked the predator a bit more, when something is worth nothing to you and you make any money off it you feel like a winner.
Good pickup!
