I have the following pedals- Morley Bad Horsie 2, TC Flashback, MXR Micro Flanger, Hardwire HT-6 Tuner, Digitech Whammy 4 and I'm going to add a Tube Screamer. Will the Voodoo Lab Pedal Power 2 PLUS Isolated Power Supply accomodate these? The jury is still out on the Whammy so keeping it is not a deal breaker.

The Whammy won't work, but still wondering about the others.

The Whammy 4 requires AC power so it cannot be powered from any of the front panel DC outputs, but it can be powered using its supplied adapter connected to the Courtesy Outlet on the back of the Pedal Power 2+.
Alternatively the Whammy 5 takes DC power and can be powered using a Current Doubler Adapter (the one with the Green end) connected to one high current output and any other output with both sorresponding DIP switches set to Normal.

The Bad Horsie 2, Flashback (it is the original single button one, right?), Micro Flanger, HT-6, and any model Tube Screamer can each be powered from any output with the corresponding DIP switch set to Normal.

I hope that helps!
