Good lookin' out. You're talking about using the 2 12v outputs with a voltage doubling cable, right? Thats a great feature. So that Voodoo 2 could power all my pedals AND the Micro synth? Would I be able to daisy chain off one of the regular 9V outputs? Under normal Voodoo conditions, if I used the 2 12v outputs to power the Microsynth, i'd be left with 6 separate 9v outputs and 7 units to power (DD7, Grunge, Fuzz, Chorus, Phase 100, Pickle, and tuner) and i'd definitely want the option to add 1 or two more pedals.
Not sure if i'm really into spending the money for the alternate setup but at least it's an option. I could do this

The white square is the Voodoo 2 and the tuner could velcro onto the top of it which would actually be cool. Ac cable would exit on the left side. Hmmm. This might work. Thanks.
