Normal tuning, Raging Speedhorn do have their own tuning but I worked it out like this. You can also do it in drop D, which I have added below this one. I believe that the actual song is only played on the bottom E string, (minus hammer ons, they are on A) but I think it sounds more powerful in power chords. This is the riff throughout the song: e|------------------------------------------------------------------- B|------------------------------------------------------------------- G|------------------------------------------------------------------- D|-10--10--10--10--10--10--------------8---8---8---8---8---8--------- A|-10--10--10--10--10--10--8h10h11p10--8---8---8---8---8---8--6h8h9p8 E|--8---8---8---8---8---8--------------6---6---6---6---6---6--------- ------------------------------------------------------------------| ------------------------------------------------------------------| ------------------------------------------------------------------| --6---6---6---6---6---6---6---6---3---3---3---3---3---3---3---3---| --6---6---6---6---6---6---6---6---3---3---3---3---3---3---3---3---| --4---4---4---4---4---4---4---4---1---1---1---1---1---1---1---1---| Drop D e|------------------------------------------------------------------- B|------------------------------------------------------------------- G|------------------------------------------------------------------- D|--10--10--10--10--10--10-------------8---8---8---8---8---8--------- A|--10--10--10--10--10--10-8h10h11p10--8---8---8---8---8---8-6h8h9p8- E|--10--10--10--10--10--10-------------8---8---8---8---8---8--------- ------------------------------------------------------------------| ------------------------------------------------------------------| ------------------------------------------------------------------| --6---6---6---6---6---6---6---6---3---3---3---3---3---3---3---3---| --6---6---6---6---6---6---6---6---3---3---3---3---3---3---3---3---| --6---6---6---6---6---6---6---6---3---3---3---3---3---3---3---3---|
