A synth...?

Does anyone know what kind of software instrument or effect WB has on the bass tracks on songs such as War Baby (and others that have a similar bass sound as this)?

@Dan Belcher Thanks! I'm listening to it now.

Apologies if this is the wrong place to post this. But I've been thinking of a WB song that had these lyrics: Still too green behind the ears to know his right from his wrong And: Never known for passing on a chance to just say hey. Can anyone tell me the name of this song and/or where I might find it? Patrick
