[sdiy] OT:Help with power problems

[frey at radioles.com]

My performances involve signal processing the double bass or loops of the double bass. I use a furman pedal board that provides several mains and a bank of 9V for pedals. It also includes two built in audio buses. Plugged into a set of mains on this pedal board is another power strip that has 7 plugs that I have moon wall warts plugged into. I have noticed that if I touch the frame of the furman while patching a cable from my moogerfoogers I get a shock! I in fact have 120vac traveling between the audio patch cord tip or sleeve and the metal case of the furman power strip. The metal case is grounded. I am wondering if I should cut the grounds from the power strip chassis?
I am a little clueless why this is happening at all. The moogerfoogers are only 9V dc and I assume isolated regulated power supplies? I will post some photo links if anyone decides to help. Thanks!
Also, if this is too OT, please recommend where I should look for help. JoeF.
