This is going to make you do a double take. Charlie Puth does not, in fact, know how to play guitar. However, that would never stop him from having guitars on the track. The man is a wizard behind the mic and will make his voice sound like anything.. even a guitar. Watching video made my brain malfunction because I'm hearing guitar. But he's doing this with.. this mouth?? Funniest part, when he does the tongue thing. Serious shredding right there. Good job Charlie Puth. You skill knows no limits.
