I used my Fender Strat with EMG-89 for guitars and bass, pitch shift the bass track down an octave and then process like normal bass really.
@domingooo: AD seems to work great for me with pretty much any style... especially metal. If you can't get it to work well you are probably the problem, not AD. I only have to replace the kick drum, which you will have to do with S2.0 too, all of the best clips of S2.0 on here are with replaced kick... and most of them also have extra snares blended with the S2.0 snare. Not saying my drum sound is fucking amazing or anything but I don't blend anything in.

Sounds pretty "strong" to me...
Here is my AD preset, you will have to send the kick out for replacement though:
