Inventor(s)Osborne; Gary T. (Indianapolis, IN); Hoover; Alan A. (Indianapolis, IN)
AbstractThe invention relates to the provision of a sustainer that is compatible with single coil pickups and stacked, single coil pickups. In this regard, feedback is substantially eliminated by processing and altering the direct electromagnetic radiation emitted by the driver. Another aspect of the invention provides a musical instrument, and a sustainer for a musical instrument that overcomes the problems with shifting forces between magnetic fields that are present in some known prior art devices and that are worsened when the driver is placed between the neck pickup and the bridge pickup. Another aspect of the invention is to provide suitable drive force and battery life with half as many batteries of some known sustainers, thereby providing a high efficiency switching amplifier. Another aspect of the invention provides that the sustainer can be enabled or disabled by one momentary contact switch, thereby providing that the major components of the sustainer are responsive to a transition in a control signal. Another aspect of the invention provides a bi-lateral driver for emitting a lateral magnetic field into the string array. Another aspect of the invention changes the harmonic content of the substitution signal that replaces the driver output signal when the sustainer is enabled. Another aspect of the invention enables the user to limit the drive current to a predetermined level.
