Answer 1

In a normal microphone there is a diaphram which gets moved by the changes in air pressure and then the electromechanic components of the different types of microphones will record the movement of the diaphram. However in an electric guitar there is no diaphram but the pickup is detecting the movements of the strings directly. As the strings of a guitar is quite narrow and are strung quite taught they do not really pick up much vibration from the changing air pressure from the sound of your voice or other instruments. This way the guitar pickup is only picking up the sounds from the strings.
