Here’s a passive, mega useful, super simple, 4 to 1 or 1 to 4 switch! It’s a two channel device with a nice clunky rotary switch (feels good) that takes 4 inputs and routes that to 1 output , or takes 1 input and routes that to 4 different outputs for manual and performance led switching and signal routing on the fly. The Frequency Central Where? does a good job to save pulling cables mid patch, which is always a winner in my book.
