How to Fix a GH3 Whammy Bar

Unscrew the screws in the back of a Guitar Hero 3 controller with a Phillips screwdriver.

Remove the back cover.

Locate the area on the inside of the controller just behind the whammy bar. It consists of a bracket with a spring and a potentiometer with three wires colored red, orange and brown running from it to the motherboard.

Locate the arm of the whammy bar. It is held in place between the potentiometer and the spring-loaded mechanism by an E-clip.

Pop off the E-clip with a standard screwdriver. Be careful to collect the E-clip, as it can fly off during removal.

Remove the whammy bar from the front of the controller.

Wrap the portion of the whammy bar that sits inside the controller with a few layers of Teflon tape seal. This tape is normally used to seal the threads of plumbing fixtures and will help prevent the whammy bar from floating in its mount.

Insert the taped whammy bar back into its hole in the front of the controller.

Slide the E-clip into place over the arm of the whammy bar in its original position.

Tighten down the screws holding the potentiometer next to the whammy bar arm in place with a Phillips screwdriver.

Replace the cover and screw all the screws back in place with a Phillips screwdriver.
