Since the release of Rock Band, there have been many reports of peripheral failures, especially with regards to the guitar controller. Developer Harmonix has come out and publicly acknowledged that this has become a widespread issue and that they are addressing it. Those that are experiencing problems with any equipment from the Rock Band package should visit http://support.ea.com/rockband.

"Many of you have contacted us regarding your guitar controllers," said a statement by Harmonix on the official Rock Band community board. "As sometimes happens when new products first go into manufacturing, we discovered an imperfection with the strum bar in an early production run of guitars that were shipped at launch. We want to inform you that we have since identified and fixed the issue in all subsequent production runs of the guitars. Harmonix is dedicated to creating 100% customer satisfaction and to those of you who've encountered any hardware issues, we are sorry for the hassle."

The company also commented on the compatibility with Guitar Hero III's Les Paul guitar controller and the lack of stand-alone guitars and drums for Rock Band on PS3. They offered no immediate solution, but said, "Please know that these issues have our full attention. We are listening and we read everything that is posted here on our forums. We are committed to providing the best play experience possible and working hard to ensure that we solve these problems as soon as possible. We promise to keep you updated and, in the meantime, we thank you for your patience."
