The question of high or low impedance for an electric guitar depends in large part what work the instrument is to do. High impedance pick-ups instead of low impedance were at first so that pick-ups would match amplifiers in use. ... band pass, graphic equalizers, etc., that are readily available (see publications like Calectro-GC Electronics Semiconductor Data and Applications Handbook). ... The use of transformers can allow the capabilities of either high or low- impedance pickups.
