Call me crazy, but we had the same issue and just for kicks, tried hooking it up the way the book says for GH. It worked. Don't use the USB receiver, just put the controller in the back of the guitar, and give it a shot. The controller and receiver are NOT designed to work together, it is one or the other.

Are you trying to plug in the yellow, red ,and white cables into blue, green, and red slots? If you are you cannot because those are for HD inputs only

does the fret buttons stick or anything?

Make sure that the Guitar Wireless receiver, microphone, and drums are connected to the USB hub provided with Special Edition. Ensure that the foot pedal is connected to the drum set. Then, perform the following:

1) Ensure you have fresh batteries in the Wireless Guitar
2) Insert receiver into USB hub
3) Turn on Guitar via switch on back.
4) If both the guitar and the USB receiver is flashing blue, then press the guitar logo button until flashing blue light on the receiver stops flashing.

Good luck!

If you are using the Fender Stratocaster Rock Band Guitar:

1) Ensure you have fresh batteries in the Wireless Guitar
2) Insert receiver into USB hub
3) Turn on Guitar via switch on back.
4) If both the guitar and the USB receiver is flashing blue, then press the guitar logo button until flashing blue light on the receiver stops flashing.

Note that on Rock Band 1, non-Rock Band guitars (ie: Guitar Hero and Wiimote based guitars) generally don't work.

Good luck!

guitar hero controllers were not meant to be compatible with rock band on wii for some dumb reason, the only rock band compatible with those guitars is rock band 2, my world tour guitar doesn't even register on rb1

For me it was the white box that connects to the back of the wii. I tried everything from changing batteries in the guitar, to pressing white button on guitar, to restarting while holding white button down to screaming at the wii. Then I bought a new rockband guitar at best buy and the new guitar did not work until I swapped the white box (dongle?) that connects to the back of the Wii. One is for the drums and the other is for the guitars and mic. Hope this helps.

Press the red button down for 3 seconds
