Thousands of happy customers disagree, and thousands more tried to out-tune the Min-ETune at MusikMesse and they all lost. I think the guy demoing it for you must not have known how to use it properly. I can go from a whole step down to standard pitch in about 3-4 seconds on the Min-ETune. I'd like to see you do that with your hands. And weighs less than a set of Grovers! I asked 15 guitarists last week why they don't play in open tunings and all of them said it takes too long to get into a different tuning. Every one of them. I'm serious. If you could be in ANY tuning you want in a matter of seconds, would you play around with open tunings more? Would it inspire your songwriting? Do you play in a cover band and hate taking 3-5 guitars a night....some of which only get used for one song in a non-standard tuning? Yes, the early Robots weren't perfect, but it was a great starting point and launching pad for the Min-ETune. All of my Robots work perfectly, and all of my friends that own them have no complaints either.
