The first batch of shipments for the Wii edition of Guitar Hero III suffered from an audio output glitch which resulted in mono sound quality even when hooked up to a stereo setup. Initially, Activision offered customers affected by the bug a free replacement disc. Now, the company is offering a full monetary refund in the amount of $132 USD to those who do not wish to wait for a replacement disc.

The required refund form can be obtained from Activision’s official website.
