Hey guys I'm looking to buy my first bass, maybe in a couple days if all goes well. Where I'm from I found a 4-string Fender deluxe jazz bass MIM, for $250 and from what I can tell in the pictures on Craigslist there isn't anything wrong cosmetically but here's my problem. I don't play bass yet so I can't really test its sound. The guy I might be buying from can't play it because he lost two fingers, which is why he's selling it. So what do I do to make sure the bass isn't crap sound wise?
