I would like to switch a couple of boards in and out of a circuit, but am not sure if I can do it with 2 switches or need 3 switches. Basically I want to switch a Treble Booster On and Off into an amp emulation board, switch the amp emulation On only (bypass the RM), or switch the Treble Booster On by itself. Below are the 2 configurations I have come up with.


I think I can get away with 2 switches only. The first version I can switch between either the treble booster or amp emulation board, with the post treble booster switch acting as an amp emulation board bypass or input to the amp emulation board. I am afraid with the 3 switch version, there could be 2 paths to the amp emulation input with the RM switched On and the Direct to Board switched on. I may have actually answered my own question, but I would like to see other peoples ideas on the matter. Maybe there is a better way of doing it.
