Short Rock groove, need help!

[CoarseBass]

I just can't make this one out, though it's simple, short, and something totally within my power...I just can't get it.

I'm listening to the Dan Lutz riff 'Overdrive Rock' here: http://www.aguilaramp.com/tonehammer_settings.htm

Can anyone give me a rough tab for this? Once I get the framework, I can make the rest happen. I think this is a fantastic riff.

And it makes me want a Tone Hammer, so its good advertising. Are these really as good as they sound? I've got an OBP3 waiting to go in my Warwick, and I'm wondering if I just should have bought the pedal...
