It makes noises with you touch the end of the cable while it unplugged? That's perfectly normal.

What kind of cable, sounds like a cheap or broken cable. Maybe a bad input jack.

Hmm, do you have a different guitar to try? Try a different cable if you can too. Which jack crackles when you twist it?

Can you solder? input jacks are super simple to replace and not very expensive.
