If you don't mind taking your guitar apart (voids warranty) you can fix this somewhat easily and cleanly. You'll need a T10 torx screwdriver, teflon tape, sharp scissors, short needle nose plies, a very small cross head (phillips) screwdriver, and a very small slotted screwdriver.

I have the Wii version so my directions apply to that.

Begin by taking the guitar apart. Remove the neck of the guitar (part w/ the fret buttons.) Remove the faceplate. Take out the Wii-mote and leave the cover off. Take out all screws including the one under the "warranty void if removed" sticker and the four on the front near the neck. Seperate the two halves of the guitar and leave it face down. Find the whammy bar assembly and CAREFULLY lift it out. Don't twist or damage the wires. They're not very flexible and must be handled delicately. You can do this by taking the whammy bar assembly apart or with it in one piece. It's not hard to put back together if it falls apart.

Firmly but CAREFULLY use needle-nosed pliers to pull the little 3/4 lock washer away from the post it's attached to. Pull straight back DO NOT try to slide it off. You may need the small slotted screwdriver to help pry it away a bit. DON'T BEND IT. You should now be able to slowly work the metal part of the whammy bar out of black plastic semi-circle it's held in. Once it's free note the white rubber compound they used as a friction modifier. This is what has worn down or was not made thick enough. Wrap this part of the whammy bar with teflon tape. I used approximately 10-15 wraps and I could've done more. Teflon tape is VERY thin. It's used pneumatics (air-tools) to prevent air from leaking. If it keeps air from leaking through cracks you can imagine how thin it must be. Replace the whammy bar in it's housing. Before you reinstall the lock washer check that the whammy bar is tight enough. If not add more teflon. If it's ok then reinstall the washer. To reinstall it, make SURE the whammy bar is all the way in it's housing. You should see a very small ridge in the metal that is for the washer. Push the washer (with pliers) straight on. It should sit in the groove. You are not looking for the washer to be a tight fit. It's only job is to prevent the whammy bar from being pulled off. Reassemble the guitar and Bob's your uncle!

Good luck. Hope this helps.
