Abstract
A magnetic pick-up device for stringed musical instrument, comprising at least one permanent magnetic element (1), round which a coil (4-5) is wound, and a string (C) of the musical instrument, being part of the magnetic circuit including the permanent magnetic element (1), so that the vibrations of the string (C) change the reluctance of the magnetic circuit and generate an induced electromotive force in the coil (4-5) that is sent to a power amplifier (2). The coil (4-5) is constituted by a double-lead winding, each extremity (7-8) of which has one end being connected to the power amplifier and the other end being free.
