I wondered the same thing myself probably a power supply issue. I like the one spot and if a pedal can't work with my pedals and very convenient 1700 mah power supply, then goodbye pedal. At this stage of the game having been down the road with a butt load of pedals on a large pedal board and not needing half of them and buying Cioks, and Voodoo Lab products to run a bunch of pedals at $$$ . I came to the conclusion hat I don't need, and can't handle more than eight different pedals at a time. I also like the grab and go size board to get where I want to go and do what I want to do, with minimal hassle. In my younger years I may have screwed with a different power supply. Thinking back on it, that's exactly what I did when I was on Strymon kick. Raye don't play that anymore.
