This is the Johnny Cash guitar trick. It’s involves folding a dollar bill or a playing card into 3 faces and inverting it to face the neck of the guitar and placing it over the last 3 strings. Once you strike those 3 strings, it’ll emulate the sound of a stroke on a percussion drum. This trick is a must know for guitar nerds. Excuse Scooby he was really amped up today probably cause the good weather 😌. #johnnycash #guitar #tutorials #music #trick
