Red Octane has responded regarding the huge numbers of problems reported regarding the whammy bars on Guitar Hero 2 guitars. Luckily they seem to isolated the model numbers of the guitars that seemed to be defective.

Here’s what Red Octane had to say,

We have isolated this issue to two model numbers that can be found on the guitar’s packaging. The numbers are 95065 and 95055. We are asking that customers who purchased their items from a retailer perform an exchange with that respective store (for a model number other than the defective two listed above). Customer’s who purchased through our online store can complete an rma request for their defective item and we will exchange it for a fully function guitar controller. We do apologize for the inconvenience and will [resolve] these matters.

Get those guitars returned and get rockin’ again.
