so subdecay's site says that if you use the noise box in your chain with a onespot/power all other pedals "MUST be negative ground". this is not so good, since i was looking forward to my DOD meat box/noise box combo. the meat box requires one of the blue 3.5 mm phone plug jumper cable, which has a positive polarity, no? am i worrying for nothing here? or can i not use my noise box in the same chain as my meat box?
