Honestly...I'm not feeling the Metallica in that...it has potential, but I think it sounds too happy...somthing about the chords you use. I don't know I turned it up as loud as I could and I just couldnt get that headbanging drive out of it...ya know it just wasn't bonecrunchy enough...I'm by no means saying I could do better I'm just saying I didn't work for me as an individual...sorry dude.
