Magnetic pick-up for stringed musical instrument

An electric stringed musical instrument, comprising:

• an elongated body having a chin end, a hand end, a top and a bottom, said body including an elongated bottom cavity, a window in said top which opens into said cavity, sidewalls outwardly bounding said cavity, and an elongated finger board portion extending from said cavity outwardly to, and including, said hand end of said body;
• a set of at least four laterally spaced apart strings extending lengthwise of said body along and above said finger board;
• key means mounted on the sidewalls of the cavity near the chin end of the instrument, said key means including string end receiving portions within said cavity and means for rotating said string end receiving portions, for tensioning the strings;
• a first bridge means extending laterally of the instrument, across the window in the top of the instrument, said first bridge means being supported at its ends by the sidewalls of the cavity;
• anchoring means at the hand end of the instrument for anchoring end portions of said strings;
• second bridge means endwise inwardly of said anchoring means,
• wherein said strings extend from said anchoring means to and over the second bridge, and from the second bridge to and over the first bridge, and from the first bridge through said window to locations of connection to the string receiving portions of the tensioning keys;
• and
• magnetic pick-up means removably mounted within said cavity from the bottom of the instrument, and including a core and a pole piece projecting from said core up through said window into a position adjacent said strings, on the hand-end side of the first bridge means.

An electric stringed musical instrument, comprising:

• a plurality of laterally spaced apart strings in tension;
• and
• a magnetic pick-up comprising a magnetic core positioned below the strings and insulated wire windings extending about said core, and a magnetic pole piece connected to said magnetic core and extending from the magnetic core toward said strings, said magnetic pole piece presenting pole regions between and laterally adjacent said strings, oriented to produce laterally elongated magnetic flux regions,
• wherein the strings are in said magnetic flux regions;
• wherein the magnetic pole piece comprises a pair of arms extending away from the magnetic core at an acute angle to each other, each of which has side portions which are positioned laterally adjacent the strings of the instrument;
• and
• wherein each arm has an end portion which is situated generally between two strings of the instrument, and which produces a flux region having a substantial component in the direction of string movement when the strings are stroked.
