Drop D tuning, little distortion. Nin style you know. The riffs in the song go like this. verse |------| |------| |-33335| |-----0| then chorus with a huge boost from guitars |--------| |--------| |--------| |--------| |-33332~-| |--------| |--------| |-33330~-| during the chorus at some points the f on the low d string (third fret) is hammed on the open string. pretty easy tune. lots of fun to play though.
