How to Sync the Rock Band Guitar Controller for Wiiby Chappy Sinclair ; Updated September 22, 2017
Like the other wireless peripherals for the Nintendo Wii, the Rock Band guitar needs to be synchronized in order for it to function properly. If you have multiple Rock Band guitars, they must be synced one by one. Rock Band ships with a USB dongle that you must use to sync and play your guitar.
Insert the included batteries into the battery compartment on the back of the guitar. Press the "On" switch on the back of the instrument.
Connect the sync dongle to one of the USB ports on the back of the Wii. Press the "guitar icon" on the sync dongle until it flashes blue.
Now press and hold the "sync" button on the dongle. While still holding the sync button on the dongle, press the sync button on the guitar. When the lights on the guitar have stabilized, you have successfully synced the guitar to your Wii.
