I have a few ehx pedals, and am sick of having to have their own AC adapter. I have used a different power source for a short period of time on one of my pedals, and it made a loud hum. It wasn’t a cable or anything. So my question is, with this knowledge of Electro-Harmonix pedals making this sound when using other AC adapters, Could I use a One Spot with my pedals, and not have to return it, because it makes the pedals unplayable?

Thanks!
