The polyphonic humbucking guitar pickup transducer comprised of multiple electromagnetic sensors, to capture the sound of each string separately of a musical instrument that uses ferromagnetic strings such as the electric guitar. The pickup works either in passive or active mode, assembled in a humbucking noise cancelling configuration and assembled as industry standard size (single-coil or double-coil guitar pickup). Each signal can be reproduced by an audio amplifier assigned for each string individually or summed in stereophonic or monophonic configuration with a high degree of separation between strings. Each electromagnetic sensor has a central core magnetically polarized inserted in an electrical coil and attached to a magnetically permeable L shape yoke which is assembled parallel with the core and coil and attached to a permanent magnet to form an efficient short length high density magnetic flux structure focused to read the vibration of each individual string area only. |
