Abstract
A sustainer is described for use with resonant strings in instruments like guitars, bases, slide guitars and others. Described sustainers can be handheld or integrated into an instrument. Sustainers under the current disclosure can include an approaching or direction detector that detects movement of a resonant element towards or away from the sustainer. Depending on the movement a signal can be fed to an output actuator that creates a magnetic field to sustain or otherwise interact with the resonance of the element.
Claims7
A stringed instrument comprising;
- a resonant string;
- a direction detector configured to generate an electrical signal in response to movement of the resonant string, the electrical signal signifying movement away from or toward the direction detector, wherein the direction detector comprises a pickup and a logic circuit, the pickup configured to transmit an output current to the logic circuit, the output current being positive when the string is moving towards the direction detector and negative when the string is moving away from the direction detector, the logic circuit configured to receive the output current from the pickup and to compare the output current to ground and to transmit the electrical signal to the output actuator, the logic circuit further configured to provide an electrical signal of 1 when the output current is positive and to provide an electrical signal of 0 when the output current is negative;
- an output actuator electrically coupled to the direction detector and configured to, in response to the electrical signal, generate an output magnetic field for sustaining the movement of the string when it is moving toward the direction detector.
