To me this sounds like a P-bass (or neck pickup of a Jazz bass) with flats, tone all the way up, and played with a pick.
Listen to the percussive attack around the 2:00 minute mark. Really does sound like a pick, no? Sadly my pick technique sucks, esp. with 16th notes.
I’ve tried getting there with very hard finger attacks, lots of EQ tweaking, a P bass, a StingRay, but I can’t seem to get that crisp snap.
