Abstract: PURPOSE:To improve the frequency characteristic, to prevent the crosstalk, to miniaturize a pickup and to improve the detection efficiency and the detection sensitivity by providing a magnetic generating circuit and a magnetic detecting circuit correspondingly to plural strings stretched on a musical instrument. CONSTITUTION:A static magnetic field H1 acts upon a strings 14 by an exciting coil 26. When the strings 14 is oscillated by playing, the strings 14 changes a reflected magnetic flux phi, and an electromotive force corresponding to the change of the reflected magnetic flux phi is generated in detecting coils 42a to 42d. Oscillation in the longitudinal direction, oscillation in the transverse direction, torsional oscillation, positional displacement of the strings 14 are subtly changed by a playing method. Detection signals Va, Vb, Vc and Vd obtained by an input detecting circuit 44 are individually amplified by amplifiers 46a to 46d and are applied to an arithmetic circuit 48. The circuit 48 synthesizes detection signals Va to Vd to obtain a pickup signal V0 indicating the oscillation of the strings 14. This signal V0 is taken out from a signal output terminal 52 through an output amplifier 50. Simultaneously a control signal CL used for processing of the signal V0 is obtained from a signal output terminal 54.
