So John you prefer the MachII/MachII setting in parallel? I'm wondering if I could get away w/modding to 2 MachII PU's w/out the extra switch, or maybe using the switch in place of the BluEqube switch.
I brought the 2 MachII's bridge and neck up to Sheldon and he didn't seem to think it was neccessary.
When I sub on bass at my churches (I usually play drums) I have some pretty big shoes to fill tonewise. One guy has a MM Anni H/S and it has low mid bite growl. We all run through a simple Whirlwind DI, very revealing.
Another guy subbed last night for us and he was using a Peavey w/2 HB soap bars and it had some nice bite but it was more in the upper mids, almost annoying, but I think everyone has some hearing loss so they like it. I wear earplugs.

At another church I sub for a guy who uses a Fender active Jazz and he's not scared of the bass boost. Lately when I play there w/my my fretless ABII-5 exclusively now I set the gain with the series setting w/bass boosted. This ensures I won't clip mid service. Then I switch to either neck or bridge soloed and boost the bass to match the original volume. The drummer was giving me a huge thumbs up. Bridge position bass boosted it's a mwah factory. Bridge position requires more bass boost to match volumewise.
I think I'd like to hear a little more low mid growl in my DW's. Don't get me wrong, they sound killer.
