First, I play this at 120 bpm with my fingers using hammer on's. Well, this riff is one that just came to me one day. I listen to alot of metal, and i dunno, maybe it rubbed off on me. Even this amazes me that i wrote it. When i play this song with my band, the guitar plays what this lesson shows, i've tuned my 5-string to a drop a, AND drop d... its' intriquite and hard to explain, and may sound silly, but if this site had options like 5 strings and different tuning, i'de be more then happy to make it a lesson
