Sometime ago my guitar started to make a crackling sound so I decided to change the volume knobs. I tried to change it my self and took everything out and left it in its case and went to school when i came back my little brother had messed with it and took everything appart. Now i dont know how to put it all together. It is a Jackson Performer with seymour duncan pickups in H-S-H configuration, one volume and one tone knob, and a regular 5 way switch. Can anyone explain how i can fix my guitar. I know how to use a solder gun.
