Boogie

I'm looking for the overdrive sound that Ben Kenney of Incubus achieves in this video [media]http://www.youtube.com/watch?v=yaLJs2xB9rU[/media] [i](from 0:02 - 0:50)[/i] I know he uses a Fulltone Bass Drive (non-mosfet) but I wasn't sure how much of the sound was to do with what amp he's using. I've never used the Bass Drive so I'm not sure if I'm barking up the wrong tree for the kind of sound I want.
