Sorry to bump an old message, but I just got a PP2+, and the proper 2-outlet-to-single-center-positive cable, and my POG 1 only powers on for a second before powering back off. Does anyone else have experience with this, and know what might be causing it? I’m going to have to just use the original wall wart for gigging for now, because I use my POG in my chain all the time.
