How does a guitar pick up work? Is it like a small microphone? |

Most electric guitars use magnetic pickups, which convert the vibration of the strings above them into an electric signal by induction. http://en.wikipedia.org/wiki/Pickup_%28music_technology%29 Most acoustic-electric guitars use piezo pickups, which sit under the saddle or nut and detect changes in pressure. http://en.wikipedia.org/wiki/Pickup_%28music_technology%29#Piezoelectric_pickups |
