Pedal-wise, i'd say a Sansamp Bass Driver with the 'Drive' cranked (drive on this pedal doesn't add distortion/overdrive, but it does add a bit of bite/growl) and also the 'Blend' knob bias towards the effected signal more than your original bass signal. You'd be able to get this tone with most basses, certainly with a P bass or jazz. Oh and Volume helps
Amp-wise (solid state), a Tech 21 Landmark series Bass amp can muster a good variation of sounds, from clean to Tool/King's X/Jesus Lizard type distortion.
