Query: guitar hero "shredder" by pro jammin

this controller was a piece of garbage since i can't use stronger language. it worked for just about ten minutes before it stopped working all together. i wouldn't reccommend it to my worst enemy. the only thing this guitar non-controller might be good for is a wall ornament or maybe if you need a target for skeet shooting. i was so angry that i didn't even bother trying to get my money back.
