does anyone know a good basline in chords plz
need something nice to play

something like the "Seven nation army" intro
i would probably suggest les claypool of primus, and his rendition of metallica's "master of puppets" as far as i know the introduction for sure is using chords the rest of the song could very well be also, but thats my suggestion.
first, seven nation army is all guitar, drums, vocal. no bass, its a electro haromonix pog/hog.
but play the song know your enemy by Rage against the machine, its a sick bassline
