I bought a russian big muff a few months ago, and recently I decided to add a 9v power jack to it. I chopped off the end of the battery clip, and connected the wires to the jack. Red to the positive and black to the negative. Although only now has it occurred to me that wouldn't this make the jack a positive tipped one? So I can't daisy chain it? Would having black to positive and red to negative make it so I can use it with my other pedals? Thanks.
