Sounds like a couple sounds mixed together...
Maybe a sampled electric bass, and a mono synth (for the lows) with a Lo-fi distortion type FX slightly mixed in. I might be way off though.
I gave it a go on my CS-10, but could only get a much fatter sound
(Am also running it through the Studer 169 pre & EQ...DROOOL) Couldnt quite replicate the clickyness of the sample, which made me think the synth used was either VA or ROMpler. Dunno...
