alright mate nice one!
bass is 2 x saw II's detuned maybe 30, maybe 35.... low cut taking anything below roughly 80Hz off, camel phat on the main bass then send to a bus with the highs brought out more reverb chorus to give it the wideness with a simple sine sub underneath!
yeah distortion mate, probably heavy on the tube distortion and possibly some xciter too!
oh and the growl is the same OSC's i think with maybe phase modulation in massive at -12 octaves!
