Abstract: The present invention provides an Effector Power Adapter for connecting an effector, the Effector Power Adapter includes a power supply module, at least one first voltage transformation module and multiple voltage output ports, wherein the voltage output port has at least one first voltage transformation output port. The first voltage transformation module is electrically connected to the power supply module and the first voltage transformation output port, and the first voltage transformation module controls the first voltage transformation output port to output numerically continuously adjustable voltages. The present invention further provides an Effector Working System, which has an effector and the above effector power adapter. The Effector Power Adapter and the Effector Working System provided by the present invention can apply different voltages to an effector to produce different sound effects, which enriches the playing effect and offers more musical creation space for music practitioners.

Abstract: A sound effect adjusting device includes: an effect pedal; a pedal board including a first housing, a three-way toggle switch, a microswitch, and a mounting member; the first housing including an input interface, an output interface, a send interface and a return interface formed thereon; the three-way toggle switch having a first contact blade electrically connected with the input interface, a second contact blade electrically connected with the send interface, a third contact blade electrically connected with the microswitch; the mounting member having a first pins assembly electrically coupled to the effect pedal; while the effect pedal assembled with the pedal board, the microswitch is off, and operates the three-way toggle switch so that the effect pedal is connected between the input interface and the output interface in series, or, the effect pedal connected between the send interface and the return interface in series.
