This is...kinda stupid, no offense to anyone that wants to actually buy it. With more of these type of guitars, guitarists, especially beginners, will find that tuning will become a thing of the past. Some things should really never change, I mean imagine seeing someone playing a guitar incredibly, and you're impressed with them and all, and they don't even know how to tune the damn thing using their ear. With that being said, it's a cool idea, I just think it will ever really catch on, it's just like a... gimmick or something.
