Abstract
A sensor assembly for a stringed musical instrument having a plurality of movable strings includes at least one blade adapted to be disposed adjacent the strings and at least one magnet disposed adjacent the at least one blade to generate a magnetic field through the at least one blade. The sensor assembly includes a primary winding disposed adjacent the at least one blade to create a primary current from a disruption in the magnetic field by the moveable strings. The primary current creates a primary electromagnetic flux. The sensor assembly also includes at least one secondary winding spaced from the primary winding and being magnetically coupled to the primary winding. The at least one secondary winding transforms the primary electromagnetic flux into a secondary current adapted to be passed out the stringed musical instrument.
