Sounds like the bass player is using a Boss SYB5 or similar, and that is being mixed with the original synth bass on the track.
Yes, the original track is a nasty synth bass with a sawtooth waveform and half-open filter that has not much or no envelope control over the cutoff frequency.
You could use a gated fuzz for the main sound, like a Wooly Mammoth or Iron Ether Oxide, then maybe a half open wah, or envelope filter with the sensitivity down to similate the filter. An octave pedal first before the fuzz would give you beef.
