Go to your local music center. If you have a Guitar Center near you go there. These cheap guitars are just that. Cheap. They don't stay in tune and can warp easily. Nothing will turn off a beginner than a guitar that sounds crappy. The best advise is to buy the game with the cord, you will need it, and then take your son to the store and let him pick a guitar out. Your first guitar becomes like your favorite pair of jeans. No matter how beat up it gets you will never let it go. Get something that will last more than a few months. A decent beginner Fender Strat will cost you $250-300 but in the long run will be worth the investment.
