so go and behold my ns-2 has been powering the rest of my pedals through the "in" input and taking the current from the wall though the "out" input if the dc parts. Now i noticed this by two things one i was always getting little shocks from muteing my strings weither it be my hand, plam, forearm anything id get a shock (was kindda funny when some didnt know about it). And two alot more feed back than i use to have. Now my only concern is at this point is my mark v, would this have done anything to my amp, if so would it have blown a tube or fuse before anything? Because if thats the case then im fine in tubes and fuses im just sketchin out because of the whole polarity thing. Thanks in advance.
