A vibration transducer device for stringed musical instrument comprising a magnetic field generating bar (32, 34, 36), metal strings (30a-30f) of the musical instrument and an electronic circuit (38) is described herein. The electronic circuit (38) amplifies a minute electric voltage induced in the metallic strings (30a-30f) by the magnetic field when the metallic strings (30a-30f) are vibrating.
