The pick-up is not a microphone, but rather a magnetic transducer. The pole piece in the transducer senses the proximity of the string to the pole piece, producing a signal at the output of the transducer based on the distance of the string from the magnetic pole piece. This way no foreign noise is picked up (background) such as sneeze, cough, etc. A recording could be made of an electric guitar in space, and played on earth to see what had been created in space. (The speakers would then have air to transmit the sound).
