A digital musical instrument company, Misa Instruments build guitars played by plucking the virtual string on the screen. Named Kitara and built for the iPhone generation, the guitar has a touch screen, music synthesizers and virtual string that can play 100 different sounds. It costs £3,200 each.
For most guitarist, I think the normal guitar is better than the stringless one. The touch of the string is best after all. Plus, this guitar is costly too.
