FYI: This is one page of our extensive Rock Band video game series coverage, to see codes for all Rock Band titles visit the Rock Band Info-Hub.
The following cheat codes are available for use in Rock Band 3 on the Nintendo Wii video game console. The codes that are available are limited to unlocking a few different guitars.
Unlockable Rock Band 3 Guitar Codes
Using Player 1's guitar controller enter one or more of the following codes while at the Main Menu. Once a code has been entered correctly the unlocked guitars will become available under the Customization Menu.
Codes are entered as button combination using the colored Fret buttons on the guitar neck. Some people feel that it is easier to read the cheat codes when abbreviated, so I have listed both the typed out code, as well as the shortened version for your convenience.
