If you're experiencing problems with your electric guitar, such as the signal cuts out when you move, it generates a hissing or buzzing noise at all times or you hear a crackle and pop noise when you touch the guitar cord, then you need to repair your guitar input jack. Always be careful when opening up the electronics on your guitar, and never pull on something that appears to be stuck because it's probably anchored by an important electrical connection.

Unscrew the input jack plate from the body of the guitar, and slowly pull out the input jack assembly as far as the wires will let you. Make sure you unplug your guitar cord from the input jack before you begin.
Bend the input tab slightly up to give more resistance to the jack and make better contact with the cord. The input tab is the metal tab that protrudes out from the jack and is shaped like a picture hanging hook. Bend it only slightly because that is all you'll need to make better contact with the cord.
Analyse the wires attached to the input jack. If they bend easily to the touch, then they are not sufficiently attached to their respective metal tabs.
Remove the old solder on the metal contact tab, reposition the wire so that it makes solid contact with the tab and solder it back in place. Use only a small amount of solder. Do this one tab at a time so you know which wire gets reattached to which tab. If you try to remove the solder from both tabs, you may not remember which wire goes to which tab. Do not touch or move the input jack assembly until the solder has cooled completely. This should take 10 to 15 minutes.
Re-install the jack assembly into the body of the guitar, and screw it into place.
Tips and warnings
- Be gentle when reinstalling the assembly after you have repaired it. If you get resistance before the plate is in place, carefully pull the plate out and start over. Do not force the plate assembly into the guitar because you could snap the contact tabs and ruin your jack assembly.
