To get back to this: while I love to get rid of the noisefloor, that's not my biggest concern. I need to get rid of the buzz, the groundloop. If I touch my guitar strings I hear this electrical pop. And when I put my face on the chassis of my rack case, I get a little shock. It's always been that way, though, no matter if I ungrounded all the gear or not.

I just want to be sure that noisefloor / groundloop don't get scrambled in this topic. So, heva, did you have a groundloop issue (buzz) or just some regular noise?
