Instantly Tuned Piano

Tuning a guitar, especially a 12-string guitar, is a delictae and time consuming process. The worse, you have to do it over and over again as a guitar gets out of tune rather quickly. In addition, perfect guitar tuining is difficult for many people. It is also distorbing for the audience during performance.

An instantly tuned guitar would be equipped with an electronic tuning device. You need just to push a "Tune" button, and the device would do the rest  – instantly and perfectly.
