Luckily my copy of Rock Band
hasn't had the guitar problems....yet.. but if you do where your down strum is having problems, you can go to this post
and maybe fix it yourself. It seems easy enough and it might be something to try before you send the guitar back. It's been a pretty poor showing for guitars in the recent weeks and it actually dates back to the 360 version of Guitar Hero 2
. Seeing all these instrument problems is a little disheartening and I hope that companies get better quality control over future guitar peripheral releases. I'm dreading seeing drum problems prop up with the amount of beating those things take.
