I was practicing through my peavy vypyr tonight wwith one of my leads and there was a very loud buzzing when I wasn't playing anything. I changed to a different lead and most of it went away. what is the problem with the lead and is there a way to fix it or does it need replacing?

(the buzzing lead was a Stagg, the other a no name brand and the guitar is an aria excel standard. This was on the 6505 setting with X boost)
I just get another lead when one of mine breaks, they aren't too expensive. Plus, if you take it to the store you bought it from, sometimes they'll replace it for free.
