Here’s a mesmerizing video that captures the vibration of the strings of an acoustic guitar from an iPhone 4 mounted inside the body of the guitar. It’s fun to watch, but be aware that the string “vibrations” are a result of the rolling shutter on the camera. Strings don’t actually vibrate that way.

Nice i want to try this with mine but i am afraid that it will get scratched up to bad
surprisingly good sound from an iphone…
