I've used a Fold6 with drive at 50% and fold just barely on to get kicks to punch specifically a ModBase09 mk2 through around 80 of 90 multi-hour techno streams. This worked well for 909 style kicks. I tried with a Unicorn Boom (808) and didn't like that much, but through a 100 Grit it got a super fat sound. So it all depends. I also use 2x TriTones with a smile curve on the master and this really helps out to get the hats, kick and sub to sound huge.
