I have been using the VooDoo Labs Pedal Power 2 Plus. What I dig about it is that it can power 9V and 18V (Mu-III, and others) but can also do 24V for EHX and run Eventide, Line 6, TC Nova effects and others I can;t think of at the moment. According to Voodoo Labs. it can run any DC powered effect. It has a toroidal transformer and each of the eight power outputs is fully isolated - no noise. I noticed a big difference in the noise level of my effects when I set it up. It also has this neat feature on outputs 7 and 8 - there is a small potentiometer that you can use to drop the voltage and simulate a dying battery. I guess some people like the tone of overdrive and distortion pedals when the battery level "sags", as they say. I thought about the the DC brick but after checking out the Voodoo Labs - made in the USA, 5 year warranty, runs anything and it's dead silent, I was sold.
