Abstract:
1. An electromagnetic pickup for a stringed musical instrument having a longitudinal first coil ( 2 , 2 ′) having a first end ( 15 , 15 ′) and a second end ( 16 , 16 ′) and a second longitudinal coil ( 3 , 3 ′) having a first end ( 17 , 17 ′) and a second end ( 18 , 18 ′), both coils having a core region made of at least one permanent magnet or magnetically permeable material ( 4 - 8 and 9 - 13 , 48 ′ and 913 ′), and the said first coil core region ( 4 - 8 , 48 ′) has a magnetic polarity opposite to the said second coil core region ( 9 - 13 , 913 ′), and a connection that connects the said two coils ( 2 , 3 , 2 ′, 3 ′) out of phase with one another, either in series or in parallel, so that any extraneous noise or hum is cancelled, characterized by the overlapping area ( 14 ) in which the two coils ( 2 , 3 , 2 ′, 3 ′) are partly overlapping each other and the core region ( 4 - 8 , 48 ′) of the said first coil ( 2 , 2 ′) is partly overlapping with the core region ( 9 - 13 , 913 ′) of the said second coil ( 3 , 3 ′), and by that the coils ( 2 , 2 ′, 3 , 3 ′) having the core regions ( 4 - 13 , 48 ′, 913 ′) are set to induce the same voltage in the overlapping area ( 14 ) that the coils ( 2 , 2 ′, 3 , 3 ′) induce outside the overlapping area ( 14 ).
