There's been some
discussions on Gamespot over faulty whammy bars in some boxes of
Guitar Hero II. The talk is that depending on the guitar you got which is determined by where the extra pedal port is positioned lets you know if you have a faulty whammy bar. By holding the guitar up on it's end, the ones that have trouble are those with the port on the bottom. If you have one where the port is on the side you're golden. Complaints of non responsiveness to having the bar just float down have been posted on the message board. From personal experience I did play one at a local Best Buy where the whammy bar was loose and would hang down. I had to continue to hold it while playing and it threw me off a few times trying to use it. Guess we'll see in the next few days if there's a problem and a recall.
