Reply To: Connect two H9s to one 2-button Aux Switch via Y-Cable?

I can’t confirm- but I bet it would. Could the common ground interfere somehow?  Maybe? You gotta try it and see.

 

I CAN tell you it would be trivial to modify almost ANY two button switch to  have two independent single switches feeding two separate mono jacks. It would take 20 minutes and $2 in parts. BUT- I bet it will work just how you said.
