Bassline of A-Trak's Say Whoa?

[Norvege]

Hi everyone!
This had been really killing me. I have been trying to do the bassline of Say Whoa and I just can't seem to replicate it. I'm just trying to get more familiar with music theory and production. If anyone out there who is more musical than I am, please help! Does he have sidechain compression on it and some pitch bend?

Thanks!
