ABSTRACT:
Two magnetically permeable pole pieces have pole faces of predetermined configuration formed thereon, and the pole pieces conduct magnetic flux which interacts with a magnetically permeable string of a stringed instrument. The positioning of the pole faces, the geometric configuration of the pole faces relative to the string, and the predetermined pattern of magnetic flux emanated from the pole faces are arranged so that vibrational movement of the string in one plane creates significant magnetic flux changes in a first pole piece and minimal or no flux changes in the second pole piece. String vibrational movement in a second plane mutually perpendicular to the first plane creates significant magnetic flux changes in the second pole piece and minimum or no flux changes in the first pole piece. The magnetic flux changes are sensed and electrical signals related to the flux changes are derived. The electrical signals are supplied directly to audio amplifying equipment.
