Anyone having a problem with interface outputs and extreme 60hz noise when trying to reamp? I've deducted it's not the amp, the TS, or the cables. The noise only comes when I try to plug into either my Saffire 14, 40, or even 56. I plugged into my guitar as well, dead silent. Just when I plug into the interface. It makes noise even if the unit isn't plugged in. Once I plug it into the unit, noise rape. Any advice?
 
Ah ok got it, when the soundcard is not plugged into the wall power...

Probably an isolation from the ground in the soundcard chassis or something... 60Hz can be filtered very nicely with Izotope RX DeHum if you can't fix the problem at the source.
 
Do you use some kind of reampers or straight form interface?
Passive reampers have ground lift switch, so transformer isolates reamper output from interface output, it`s very helpful to remove 50 or 60 Hz hum.
