Watch the Chuggin' Puppet online guitar lesson by TrueFire from Rhythm Guitar Greatest Hits Vol. 1
James Hetfield is the undisputed heavyweight champion of metal rhythm guitar--no question. His contribution to the art of playing, not to mention composing, metal riffs is beyond category. If you were to study the method behind the madness, the first day of class in Hetfield 101 would have to be an exploration into alternating between muted open 6th string chugging and fretted notes on the 5th and 6th strings. This MUST know riff does just that. With a dash of chromaticism thrown in, this riff points towards the larger-than-life riffs in "Master of Puppets"--Metallica's "Stairway to Heaven".
