I have all four factors as well. I am also curious if there are any options out there to power all four simultaneously. In our case it defeats the purpose of buying the power factor if you still have to use one wall wart on your board. The only pedals I use are the Eventides and the four wall warts are kind of a hassle. I am truly a rack guy at heart and always have been but since been converted. I like the flexibility and portability these pedals offer without needing a midi pedal. Now if we could have just one power supply to cover all the exiting pedals and maybe room for some future ones it would make a lot of people happy.
