ABSTRACT:
A device and method for automatically controlling accessories connected with a musical instrument. A switch on a movable arm of an instrument stand indicates the presence of the instrument. The switch is normally closed activating all connected accessories unless the instrument is placed in the stand. The placement of the instrument in the stand opens the switch, turning off the power to the accessories. The entire system is set up and then locked out to prevent unauthorized use of the instrument. A battery in the instrument powers a transmitter also contained in the instrument. Thus, is eliminated the wearing of a body transmitter by the performer or a direct line connection. A charging unit is built into the device to automatically charge the battery in the instrument during the time the instrument remains in the stand. Battery replacement is eliminated. A method for improving sound from an instrument comprises encasing the magnetic field coil within a permanent solid material.
