A sensor assembly for a stringed musical instrument having a plurality of movable strings comprising:
- a case having a longitudinal channel;
- a primary magnet disposed in said longitudinal channel;
- at least one coil disposed in said longitudinal channel;
- and
- at least one secondary magnet disposed in said longitudinal channel between said primary magnet and said at least one coil.
A sensor assembly for a stringed musical instrument having a plurality of movable strings comprising:
- a case having a longitudinal channel;
- a magnetic lining disposed in said longitudinal channel;
- at least one coil disposed in said longitudinal channel;
- and
- a plurality of secondary magnets positioned in said longitudinal channel between said magnetic lining and said at least one coil such that magnetic fields created by said magnetic lining and said secondary magnets are constructively added.
A sensor assembly for a stringed musical instrument having a plurality of movable strings comprising:
- a case having a longitudinal channel;
- a magnetic lining disposed in said longitudinal channel;
- at least one coil disposed in said longitudinal channel;
- at least one secondary magnet disposed in said longitudinal channel between said magnetic lining and said at least one coil;
- and
- a plurality of comb pieces disposed within said coil for locking said coil within said longitudinal channel.
A sensor assembly for a stringed musical instrument having a plurality of movable strings comprising:
- a case including a base wall and at least two side walls extending outwardly from said base wall, said base wall and said side walls forming a longitudinal channel;
- a magnetic lining disposed in said longitudinal channel along said base wall and said side walls;
- at least one coil disposed in said longitudinal channel;
- and
- a plurality of secondary magnets disposed in said longitudinal channel and adjacent said magnetic lining and adjacent said at least one coil such that magnetic fields created by said magnetic lining and said secondary magnets are constructively added.
