More experimenting and I think I REALLY like the Empress Bass Comp with the mid-bump color switch into the DCX Bass. That slight mid-bump complements the bass/treble controls happening in the DCX. Used with the Tone Hammer, the I preferred Empress Comp color switch simply off.
I kinda lurk here, just to see what people are trying out with their boards. I've found I also really like the color switch engaged on my Empress into my drives. I also just recently turned off the 'color' with the internal dip switch, and I think I prefer it that way, but the difference is subtle in my setup.
I'm also running an Empress ParaEQ mkii towards the end of the chain, and I did some A/B trying to see how things would sound with the EQ bump would sound at the end. With that mid bump post-drive they tended to sound a bit harsh, almost to the point that I'd rather not boost at that frequency. The downstream drives really like that extra bump into them at that frequency, they get more bite and it helps them cut through mix.
It's to the point that I've been looking at a dedicated mid-eq pedal (nano-para, maybe even a RFE) so I can try out different comps! I've also seen at least a couple people running something like the Aguilar DB 316 into a preamp with the typical 2 or 3 band EQ to have a little extra control. Try putting that thing earlier in the chain, ahead of your drives! Your clean sounds will be the same, and you might find something really nice happening.
