First off, you need to place your X Plorer controller face down on a table or sturdy suface and remove all 11 of the black screws from the white body of the controller. You will need a long and thin screwdrive in order to do this.

Then once you've removed the back from the controller you need to locate the whammy bar's sensor mechanism.

The next step is to slightly loosen the two screws that hold the sensor in place.
