I believe this is the pinnacle of power supplies. Since introducing this model, I've no longer been troubled by noise. The sound of my effects pedals has become clear, as if a veil has been lifted. I have confirmed that both units supply power from all power outputs. The included accessories are shown in the second image: Zuma and Ojai units A cable to connect the two units A 3-core power cable for the Zuma Five unused DC cables The Zuma has some minor scratches. Please understand that this is a used item before purchasing.
