Abstract
Stringed instrument pickup and active switching circuitry that provide improvements in pickup sound combination, hum rejection and overall electronic function. The circuit employs plural pickups, a selected combination of which may be selected by a rotary switch. A latching device controlled by the switch outputs then produces a combination of control outputs to energize selected different FET switching devices to enable pickup signal outputs. Combined pickup signal outputs are then mixed and buffer amplified in a final output stage.
