The Gibson Robot Guitar. No, it doesn't unfoldand help you save the world from the Decepticons, but it will help your frustration level when your guitar slowly goes out of tune while playing it. Why? Because the thing freakin' tunes itself.
That's right. The. Guitar. Tunes. Itself.
Don't believe us? Watch the video titled "Instructions" here. And, while you're there, why not take a look at the amusing video ads for the guitar and then take their challenge to "do better" and come up with one yourself and submit it on the site.
Seriously, what's next? A guitar that plays itself? Are musicians becoming obsolete?
