Re: Automatic Tuners?
After hearing how the older Gibson Robot Tuning system worked, I can say people are at least trying. The older Robot Tuning system had the main piece in the control cavity, with wires going through the body, through the neck, and then to the headstock. That already sounds like a headache to me, and while I wouldn't buy anything with a MinETune, Tronical Tuners, etc., at least they are trying to do something new.
But I still think it is ridiculous that people need robots to tune their guitars for them. If I were to have multiple tunings in one show, I'd try bringing different guitars, changing to keys of alternate-tuning songs to keep everything in one tuning, or simply tune the guitar to an alternate tuning during a break/bass/drum solo/etc. before I'd try a robot tuning mechanism. Seems like a needless expense that can present problems when trying to fix something that really isn't much of a problem to begin with.
An instrument though that WOULD benefit greatly from automatic tuners would be the oud. There is a joke that a oud player will spend more time tuning their instrument than they will playing it. 12-string guitars may also benefit slightly from it, just because it takes twice the time to tune to that of a regular 6-stringed guitar. There'd probably be a market for automatic piano and percussions tuning as well.
