This commercial for Tronical Tune seems like it could have been cut directly from Back To The Future.
The device tunes a guitar completely by itself, the same way an automatic transmission does all the gear shifting for the driver.
Andy Williams of Every Time I Die demonstrates the ease of the self-tuning device by simply setting his guitar to drop D tuning, and watching as the servos automatically and exactly twist and tighten the guitar strings for the perfect sound.
Guess and check tuning will soon be a concept of the past.
