Passive 1-to-4/4-to-1 switch

Where? is a passive 4-to-1/1-to-4 switch.

Where? is a two channel device with feel-good clunky rotary switches that take 4 inputs and routes them to 1 output , or takes 1 input and routes that to 4 different outputs, enabling both manual and performance led switching and signal routing on the fly. This saves you from having to pull cables mid patch, reducing fumbling and keeping you in the flow of the beat!
