I use alot of the IMA presets as they are into a markbass 212. I really like the way they come from Ian. I also have like 30 synth presets that do not have any amp or cab on them and they sound fantastic too. None of it makes much sense to me, but it sounds fantastic in the phones and through the Markbass. I am now a subscriber to the "if it sounds good, go with it" approach.
