This invention is related to a magnetic pickup device for stringed musical
instrument with one or more metal strings made by magnetic permeable
material. The magnetic pickup device presented comprises of at least one
signal picking coil for sensing of the mechanical vibrations of the
strings and at least one large free shape low impedance coil for noise
cancellation. The signal picking coil and the large noise picking coils
are permanently connected in series in a way that the noise signals
created by the two coils have opposite phase orientations and they
effectively cancel each other.
