Set a switch to the Output 1 Volume CC#. Remember to save each MM preset w/ switch on, unless you want the preset to initially be muted.

Maybe I am missing the point but can't you just create an IA switch to turn on tuner in the Axe Fx and set tuner to mute?
That also works if out 2 echo = input 1, which is probably the best choice for a tuner feed. Plus it allows the option of tuner mute = input for normal effect trails instead of immediate muting.
