Doesn't really sound that complicated to me. You could quite easily do it in Thor (or pretty much any synth for that matter). Just create a plucky moog style bass synth sound (saw wave, 24db low pass filter, an envelope modulating the cutoff with zero attack, sustain, release and a fairly quick delay. Then layer a sub osc (sine or triangle) one or two octaves below.

Reason: changing word "delay" for "sustain".
