Abstract: A musical instrument comprised of discrete detachably assembled components permitting easy change of said components. The instrument is provided with a center section and a main body section which furnish the central core for the interconnection of component parts such as the neck, multiple pick-ups and an electronic control module. Appropriate electrical connections are automatically made when the components are placed together.

Abstract: An anti-theft system which is armed only when a hand-held coded transmitter is operated; the system is disarmed upon a subsequent operation of the transmitter. Whenever the transmitter is operated, the horn beeps, and the lights flash; this provides both verification that the system is armed, and serves as a car-locating aid in a parking field. Tampering with the automobile results in intermittent beeping of the horn and flashing of the lights. The horn beeping may be disabled during the verification and car locating sequences, while still operating if unauthorized access to the automobile is attempted. Other features include disabling of the horn beeping by momentarily turning on the ignition; beeping of the horn after the system is disarmed and a door is opened by the operator if, during his absence, unauthorized access was attempted; locking and unlocking of the doors with transmitter operation; and detection of unauthorized access attempts by sensing vibrations in the vehicle radio loudspeakers.
