How do i get rid of the humbucking noise hum?

For you, electic guitars junkies. As you know I have just replaced my pickups with the Seymour Duncan hot rodded pickups. After bringing it to the studio, there was this big hum noise after I plugged my Les Paul to the Marshall amp. I took the guitar home and after scouring the net, I finally the found the Seymour duncan site and a couple of hits recommended me to solder the ground to the tremolo. This happened to be a loose wire which I did not connect (cos I did not know what was it for ). Now, the noise is far less but since I use the push-pull pot, when it is pressed, there is some noise but pulled the noise disappears. Would appreciate any advice on this.

You can try it out and purchase the Humbuckers and push-pull pots from  Musicians’ Friend ,Music123 , ZZsounds orWoodwind and Brass .
