If there's one thing we've learned here at Crave, it's that there's an infinite number of ways for middle-aged men to embarrass themselves. Yesterday, for example, we learned of a way to make air guitar come to life (shudder).
But if you want a more conventional way to make a fool of yourself, this USB electric guitar from ThinkGeek might be more appropriate. The iAXE is a full-sized instrument that plugs into your computer and comes with software that simulates effect pedals and amps.
Mercifully, the $100 guitar is also designed to work with headphones--thereby limiting the effects of ensuing humiliation.
