Mechanix- Megadeth

[herrly]

Okay, my buddy's band is doing The Mechanix by Megadeth. They want me to play bass for them. I'm all cool with that... but I can't figure out one piece in the song. In the intro, after the drums, bass and second guitar come in. There's this part that the bass does, its a cool little quick riff he does when the guitar's notes are just ringing out. I cant seem to figure it out, I tried just listening to it and learning it by ear but my ear sucks real bad. I really wanna play this song and I really wanna play that one part in the intro, it sounds so cool. So any help?

And if you don't know what I'm talking about, its like around 13 1/2 seconds into the song.
