Activision/RedOctane have sent out a free faceplate as compensation for users who had sound problems with the Wii edition.
The original Wii shipment had dodgy sound, and for a game that requires huge emphasis on tantalising the ear buds, the company decided to ship out replacement discs out. However, the kindness doesn't stop there! According to Kotaku, those who sent in their discs also received guitar faceplates to make up for the long wait - a funky red fire/phoenix design to add some graphic style to the plastic music machines.
