Hi, I just bought a Pedal Power 4x4, and I'm wondering about the two 9V - 12V paired outputs. Is it possible to use 2 9V pedals in these? I know you're not supposed to use different voltage than those specified, but since I need all 8 outputs and the user's guide seems to say that all outputs can power 9V pedals, I prefer to ask before I actually try it...
Here's the pedals I use, if it can be of any help:

MXR Super Compressor
BOSS DD-3
Empress Tape Delay
VFR Old School Tremolo (white face version)
TC Vortex Flanger
Zeygot Fuzz (may be removed to fit a Electro-Harmonix Freeze pedal instead)
ZVEX Fuzz Factory
Crybaby

I know the Empress Tape Delay and the Vortex will use the 400mA outputs for sure, but could I use the aforementioned 12V outputs in the paired outputs for, say, fuzzes or Comp? Otherwise, I guess I'll have to let these 2 outputs empty, but I would be happy to power all my pedals from the Lab...

OK, after doing some reading, I found out I just can't use 12V outputs for 9V pedals. Forget it I asked, thanks!
