Fantastic... I'd hate to have to show someone how it works though, all a little confusing at first take. I remember seeing an overdubbed Youtube about it a month ago. The only drawback for me would be the size (& possibly weight) of the tuning heads... and I'm assuming this upgrade would double the cost of your instrument?
I guess it could be cool for quick access to alternate tunings, thus replacing several stage guitars, but sometimes you'd want not only a different tuning, but a whole different sound. And if you break a string, you still need a backup guitar.
my vote - meh
this one's special, this is the ultimate, after this i'll never need another amp, EVER... starkAM
My vote is stop spending money on advertising and coming up with shitty gimmicks, get the fuck on with making quality guitars, those things you USED TO MAKE!
p.s it's actually kind of cool, but doesn't need a media shitstorm to support it.
