Many already know this info, but Louis (The Tone King) has some good info here.
I have the second pedal he unboxes, the Pedaltrain 2.

Mine has the Voodoo Power II brick, but Pedaltrain now makes their own power supply.
I may get another board with their brand of power supply, and put one together for my son.
He currently has two pedals plus the Polytuner from TC Electronics.
