Hi, I am currently powering my pedals with a Boss PSM-5 Power Supply and Master Switch. It works well, but takes up a pedal space on my board. I want to replace it with this. It is a 1 Spot I got from my brother. He modified it to run two pedals without a daisy chain. The Boss power supply I'm using has the plug that you normally plug into a pedal, in other words the end does not look like this. I want to take that cable you see, cut the other end off, and wire it into the 1 spot so I can connect it to the Boss daisy chain, instead of buying another daisy chain. I have a meter, I just need to make sure I wire it center negative. Any help would be appreciated.
