There are few musical styles these days where the instruments are played in a purely acoustic fashion. In the majority of styles instruments are amplified when played in performance. So the topic of pickups and other transducers is pretty important to builders of stringed musical instruments. This page contains construction details and general information on pickups and transducers, onboard preamplifiers (preamps), and various other electronic circuitry that sits between the instrument and the people listening to it.
