LOL the video is hilarious, that is possibly the second-worst version of Star of the County Down I've ever heard (I shudder to think of the worst)

My instant reaction is what a completely stupid idea- he could have learnt to play properly in the time it took to invent that device.

Then I thought actually it could make guitar accessible to someone who'd be unable to finger it properly, such as a couple of members of the music group for adults with learning & physical disabilities who have guitars and really struggle with the left hand fingering.

Then I thought, but it would also make the guitar accessible to the "differently talented", or just plain lazy, who could then learn to play really badly with minimum effort. Just like Guitar Hero, but with an acoustic guitar.

Then I thought AAAAAAAAAAAARRRRRRRRRRGHHH!
