The problem with many console games or games that require specific devices is that once the controller or device breaks, then you can no longer play the game. When this guy's Guitar Hero guitar broke, that should have been the end of the game. Fortunately, this man is a natural engineer and fixed his problem with a simple tennis racket. Now he can get back to rocking and rolling.
Who knew that a tennis racket would be the solution to a Guitar Hero problem? Now he can rock his solo and wreck at the tennis courts at the same time.
