a guitar with a perfect sound. The only difference between it and any other top of the line guitar of its class is it has no steel or nylon strings. It still plays, though. How? The "strings" are digital, and the fretboard is electronic. It'd be the same technology as an iphone or other touch-screen device. Other sounds could be replicated as well, and tuning would be no problem, with a digital tuner bringing the string to the tuning you desire.
