Amps:
Gallien-Kruger RB series - nope, no way, no how
Ashdown ABM or MAG - again, nope
Anything SWR - some times you can get close, but only about 80% of the way there
Eden "World Traveler" rigs - another large hole
FX:
Any of the DarkGlass, but most especially B3K, B7K, Super Symmetry, VMT
Mutron iii
MXR Script Phase 90 -- there's certainly close, but the MXR brings something special
Malekko B:Assmaster or Way Huge Pickle (tying into the earlier discussion about the lackluster fuzz offerings)
Any good octave pedal (Digitech Drop, or OC-2)
EHX Bassballs
Ringmod - Dr. Scientist BitQuest is a GREAT one
Bitcrushing - Dr. Scientist BitQuest is actually great at this as well!
That's all I can think of off the top of my head, without being in front of my pedalboard and Axe-Fx II/AX8 setups
