{"product_id":"boss-us-20-gk-unit-selector-footswitch","title":"BOSS US-20 GK Unit Selector Footswitch","description":"\u003cp\u003eThe BOSS US-20 is a floor-based unit selector for a guitar equipped with a 13-pin GK-compatible pickup system. It lets one compatible guitar connect to two GK IN-equipped processors, such as guitar synthesizers, V-Guitar systems, or Guitar-to-MIDI interfaces. The US-20 provides practical control when a player wants to move between two connected GK devices without reconnecting cables.\u003c\/p\u003e\u003cp\u003eTwo onboard footswitches support direct performance control. The A\/B pedal selects either the device connected to Unit A or the device connected to Unit B, while the BOTH pedal enables both connected devices to be played at the same time. Status indication identifies the selected output or combined-operation mode.\u003c\/p\u003e\u003cp\u003eThe US-20 is a routing and control accessory rather than an audio effect or amplifier. It does not add an EQ, distortion, or modeled sound of its own; its purpose is to manage GK-system signal routing between compatible equipment. This makes it useful for players building a multi-device guitar-synth or processing rig.\u003c\/p\u003e\u003cp\u003eA durable metal enclosure supports pedalboard and stage use while keeping the controls accessible underfoot. The unit uses dedicated 13-pin GK connections for its GK In, Unit A, and Unit B ports. Power is supplied through the 13-pin connection from the device connected to the Unit A connector.\u003c\/p\u003e\u003cp\u003eFor system expansion, connect the GK-equipped guitar to GK In and connect compatible processing devices to Unit A and Unit B. Unit A must be connected for the US-20 and the GK pickup system to operate. Two 1.2-meter C-13D GK connecting cables are included for linking the selector to compatible units.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne GK Input:\u003c\/strong\u003e Connects one guitar with a 13-pin GK-compatible pickup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual GK Outputs:\u003c\/strong\u003e Routes the guitar system to two compatible devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA\/B Footswitch:\u003c\/strong\u003e Selects the Unit A or Unit B device.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBOTH Footswitch:\u003c\/strong\u003e Enables simultaneous operation of both connected units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e13-Pin GK Connections:\u003c\/strong\u003e Uses dedicated GK In, Unit A, and Unit B ports.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal Construction:\u003c\/strong\u003e Provides a durable enclosure for floor-based operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe US-20 is housed in a durable metal floor unit with two foot-operated switches and status LEDs. Its compact chassis measures 160 mm wide, 134 mm deep, and 38 mm high, with a weight of 0.6 kg. The design is intended for use alongside GK-compatible guitar processing equipment.\u003c\/p\u003e\u003cp\u003eConnect the guitar's GK pickup system to the GK In connector, then connect compatible GK IN devices to Unit A and Unit B using proper 13-pin GK cables. The device connected to Unit A supplies power through the GK cable, so it must be connected even when using only one device. Keep the total cable run from the pickup through the US-20 to either connected unit at 10 meters or less.\u003c\/p\u003e","brand":"Boss","offers":[{"title":"Default Title","offer_id":45669348900934,"sku":"US-20","price":453.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71FvluYL65L.jpg?v=1784493117","url":"https:\/\/audiowatt.store\/products\/boss-us-20-gk-unit-selector-footswitch","provider":"Audio Watt Store","version":"1.0","type":"link"}
