This might be long, but perhaps it can help you cop this sound.
So there's a few things affecting the sound of the bass on this track:
You might already have done this but just in case... His bass guitar is tuned down two whole steps (C, F, Bb, Eb).
Which gives it that characteristic floppy sound. Definitely sounds like roundwounds with a heavy pick. Perhaps because of his tuning he uses heavy gauge strings (that I don't know).
My guess is that he probably recorded this bass with both a mic'd up and heavily cranked SVT as well as a direct clean line (DI) into the board.
Allowing the engineer to mix, process and eq the two signals separately and build this monstrous, yet defined sound.
So with that in mind what I think you can do to get close to the sound: use roundwounds, down tune 2 whole steps, use a heavy pick.
Then get the sound as close as you can with your VT Pedal. If you have the VT Bass DI, play with the BITE button and the Blend knob.
(BTW the VT Bass DI would be kinda of ideal to get you closer to his sound, that blend knob is a God send).
I would then try compression (I would try both before the VT pedal and after and see which one works best).
Not sure what compressor you have but I think low compression (to even out the peaks and valleys of your signal), with a slow release and semi fast attack should do (adjust threshold to taste).
Last item in the chain would be an EQ (ideally a multiband graphic eq). Here you can dial-in, and fine tune your lows (30-60 Hz) and low mids because this is where the tone of this track thrives in.
Add some high mids around 700-900Hz to add some bite and definition to cut through. (I also hear a hole carved out in the mids around 300-600Hz or so, probably where the meat of the guitar and vocals exist).
Lastly, all tho I don't hear much of it on this track; look at dialing a bit around 2 to 3khz to get the pick sound for added definition (Warning this can also add string noise, specially if you have fresh roundwounds).
I lied, one more thing.... What speaker cab you use matters. I believe this guy used the big SVT 8x10 fridge.
So if you are trying to reproduce this through a 15 you'll have a much harder time doing so. (VT Bass pedal cab sim is supposed to be voiced to mimmic a mic'd 10 inch speaker,
which I have successfully done through a 15 inch speaker before... But it's never the same as using 10 inchers). So a 4x10 cab would probably be a smart choice.
Sorry this was long, but I put in a much detail as I could
Good luck!
