This is plain amazing. I have seen countless people played guitar infront of me and infront of TV. Never once did I see how the string’s of guitar actually react to guitarist strum.
This young guitar, put an iPhone 4 into his guitar, and recorded how string oscillate when you strum on guitar. He actually accidentally found it out when he was trying to record his guitar playing via an iPhone 4. Be sure to check out the video as it is really very cool.
