I got a NAC recently, and changed the two prong power cord to a 3 prong US grounded one. The cab showed up with all the ground wires inside the control panel disconnected, after reconnecting them I noticed a wavy interference on the monitor. The interference only shows up when the wire connected to this screw is grounded (not my pic):
So right now I have everything grounded except for that one line. Any ideas if the interference can be fixed while still keeping everything grounded? If not, is it safe to leave this part floating?
