For anyone who has, or is planning on purchasing Guitar Hero 3 for the 360. I strongly suggest holding on to your receipt. Upon setting it up and sitting down for a few songs I noticed something. The "Green" button was entirely unresponsive, couldn't get a response to save my life. So, I called the store to get them to secure me a replacement, and I was informed that this seems to be a fairly common issue. I was the 3rd person to claim a defective guitar today. So, if you've got Model #: 95123 805 keep an eye on the little bastard, it just may stop loving you sooner than you think.
