Great news to the guitarists because a new state of the art robot guitar was invented to change the guitar tuning faster during a performance. So when a guitarist is performing but then got trouble in the middle of the show he doesn't need to adjust the tuning pegs that is not tune properly but by simply pulling the tone controls it will automatically go back to normal tone. The tiny electric motor under the keys are being turned by a computer inside the body that listens to all the strings. It is transmitting the data and the voltage to run the motors through out the strings. Amazing isn't it? The fact as well was the guitar robot was sold out on it's first release. Some renowned guitarists such as wooten clan, metallica and more are using it. It's cool. Try it and feel the coolest tuning gadget on earth.
