It doesn't _require_ a $7,000 bass. It requires an amazing amount of skill and practice.
I have Victor's instructional video, and if I didn't see it myself, I wouldn't believe it.
I can play through the beginning well enough until it hits the 'double thumb' section. The video shows him playing it fairly clearly. He specificially goes into his technique during that song.
I've been spending a little time on that double-thumb technique. Can't do it yet. Basically he says, "Don't bounce your thumb. Slap THROUGH the string, so your thumb comes to rest on the next string down. Then use the edge of your thumb/fingernail to pull off on the string."
I've had a hard time learning it. (I'm not much of a slap player, but I'm working on it. It's fun to do, but not really my style.)
The first part is easy. The second part - where he adds the hammering, only takes a little practice. The third part - where he adds the pull off - is where it gets really hard. The third and fourth parts after that are just some kind of abomination. ;-)
What I've found is that between the OLGA tab, the recording, and the video, I've got the signature riff going pretty well.
But damn... $50 for that video at Mars. That's a bit steep.
