I just got this ebs octabass (from another TBer through the wtb threads), and while checking the battery the black wire came right off of its solder point. Bumbed! I'm of the opinion that this wasn't his fault, just the luck of the draw. I've never done any soldering on points this small...should I try, or just track down a wall-wart jack and power it that way? Geez, I'm really not happy about this. I was having a lot of fun playing through it up until about 10 minutes ago.
