Omg I have a resistor box made by TBI that has interference issues for piano notes and other high frequency noises. I believe it is based on the first Picture and I believe it is bare wire for the ground. Could this be my problem? I even sent the box back cause it has been bugging the heck out of me.
All I need is a cable shield? Omg:-D
