Abstract: An electric stringed musical instrument is formed of a body section adapted to detachably receive an interchangeable neck section. The body section mounts the electronic tone and volume controls and includes the electromagnetic pickup which is rendered into operative proximity to the neck strings when the instrument is in the assembled condition. The body section is adapted to interchangeably receive neck sections of various string types and fingerboard widths and the electromagnetic pickup is selectively moveable in the longitudinal, i.e., horizontal direction and also in the vertical direction to accomodate the particular string characteristics of the interchangeable neck section.
