Fedde Le grand vs Eniac Back n Forth Bassline

[Matador19]

been trying to get this bass for a while now, but cant get it to slam as hard as this does, im using NI Massive in Ableton. Ive been putting an LFO/Envelope on the pitch bringing it down and messing with the decay but cant get it to sound full enough, I think there might be distortion being involved?
