OK i got the tac double range v3 guitar, and i would highly recommend it because it lasted me about a year. every other guitar hero controller i bought messed up at about the time the warranty went out. ether that or i would void the warranty trying to fix it. but my problem is i played frets on fire on the computer and it started messing up. it works for guitar hero 3 only and its supposed to work for almost all the guitar hero games, and rock band. i think its the wireless receiver, but i was wondering if  anyone know how to fix this. and I'm sorry if i did anything wrong. I've looked every where and couldn't find anything, so if any one knows tell me.
