I messed around for a little bit and i made a similar effect. i looked through the synth bass presets i have and found a sub bass that sounded similar to the one in the song. I messed with the cutoff and sine to match it up a little closer.
then i used the stock chorus plugin (in logic) and turned the mix all the way up and the rate to around 0.5 hz. I'm not sure what plugins you have so you might have to mess with them a little bit.
i also used a phaser plugin and just left it on default. you will may have to adjust it. i had it at a very slow rate going left and right with the mix pretty low.
if you are using a different daw than logic or garageband screenshots may not help as much but i thought i would include them in case.
