Ok, heres some riff's from the Offspring song "No Hero". They should be
pretty accurate. I didn't put in any rhythm or anything so you'll have to
listen to the song to get that.

Intro/Verse Riff
E|----------------------------|

G|*----11--12--7--9-----7----*|
D|*-9--11--12--7--9--7--7--9-*|

Chorus Riff
