If you're one of the unlucky souls cursed with a bum strum button on their Rock Band guitar, you might not have to send it back to EA just yet. Ben Sones over at Quarter to Three got a gimped guitar and tore it apart to try to fix it himself. Apparently, the issue's actually pretty minor: One of the strummer's microswitches has just rotated out of alignment. A quick adjustment to the screw holding it in place and you're ready to roll. The disturbing part is the uncertainty over whether it's a production issue or a design flaw.
