I'm also in the WARM camp. And usually coupled with the SCOOP input. I keep experimenting with different combinations, gain levels and EQ settings, but I know I have at least one very reliably pleasing combo in the following:
WARM
SCOOP
GAIN @ 5
EQ to taste as needed.
I usually run a Source Audio Zio Bass in front and when I do that:
TREBLE @ NOON // MIDS @ NOON // BASS @ NOON
Current EQ without Zio (practicing at home, likely will change at rehearsal):
TREBLE @ 1:30 // MIDS slight cut @ ~650k // BASS @ 12:00
