If you and your glam rock bandmates go through a few costume changes during every performance, now your guitar can join you with its own wardrobe malfunction. Here's the Wave Guitar from RKS Guitars, the first ax with an interchangeable pick guard and body shell. Just unscrew the old skin and replace it with the next color, and you're good to go in just a few minutes. The handmade-in-the-USA guitar is $899. Wonder what it looks like naked?
