Abstract
A magnetic pickup for an electronic amplification system of a stringed musical instrument wherein the variable electrical signal produced in response to the string traversing the lines of flux from a permanent magnet is generated by a Hall effect sensor, thereby eliminating the usual inductively coupled coil(s). The invention is disclosed in embodiments employing bar and horseshoe magnets with the sensor positioned on the opposite or on the same side of the magnet as the string. The sensor is an essentially planar device which may be positioned in a plane substantially normal to the lines of flux in contact with or spaced a predetermined distance from the associated magnet or positioned in a plane non-perpendicular to the lines of flux, or adjustably positioned with respect to the direction of flux lines to achieve the desired degree of sensitivity.
