Design features for bass guitar pickup |
Vityuk Alexander A.
The article discusses the design features of bass guitar pickups that provide practical application of the instrument in modern music. The principles of classification of functional parameters of electromagnetic pickups in the context of their division by device types and types of electric signal generation are studied. The key aspect is the processes of sound formation carried out by the vibrational movements of a metal string in a magnetic field, the presence of which activates the permanent magnet of the pickup. Special attention is paid to the difference between the sound and timbral characteristics of electromagnetic pickups for bass guitar, passive and active electronics, as well as to the preliminary conversion of the received pickup signal inside the electrical circuit by means of an installed timbre block. In addition, the main types of Ceramic and Alnico magnets used are analyzed, which in turn are grouped by a certain chemical composition and are divided into subspecies. The author emphasizes the evolutionary direction of fundamentally new piezoelectric pickups for bass guitar that convert the mechanical energy of string vibrations into electrical energy. Evaluates MIDI pickups that allow you to take an Electromechanical signal from each string separately and digitize the resulting MIDI signal by sending it to synthesizers. At the same time, the most advanced design of optical pickups and the specifics of their operation are being studied.
Keywords: pickups, bass guitar, single coil, humbucker, sound extraction, electrification, guitar construction.
