I finally got around to adding my rack-mount tuner into signal chain. So instead of guitar plugging into INSTRUMENT in the front of AXE-FX, I am running guitar into rack tuner, and tuner-out into AXE-FX rear input (Input 1) . I switched the appropriate setting to recognize the input from the back of the unit. But in trying to set my input levels- (Instr In, Input 1, Input 2), I notice that these actually do not affect the sound level output at all. I would expect that if I turn down Input 1 to ZERO, I would get no sound out. Or if I increase it, it would make my output louder.
What am I missing?
