By the way, I contacted SD and left them a message. I will let you all know what I hear.
I haven't heard back from SD yet, but after going through eight pages of google I came to two possible answers:
A: The noise is normal because my body is acting like an antenna and amplifying noise around me like if you touch the end of a guitar cable when it is plugged in. (Same noise.)
B. I need to reverse the positive and negative cables. (I think this is less likely because the green and bare would then both need to be hot and the single black would become ground.)
Anyone else with ideas? I touched the poles of my PAF Joe and X2N and heard a little noise like what I was dealing with. I also wired those so that could be an issue. 😀 I tried some guitars here at work and they did not make noise when I touched the poles. They could be lower output too. No definate answer yet.
