How do I set up Mobius Pre/Post Mode in a chain of pedals?

This info is available on page 23 of the User Manual.

Set the PRE/POST switch to the down position to use Mobius in a pre/post type setup.

Connect INPUT 2 to your other pedal(s) output and OUTPUT 2 to the input of your amplifier or other pedal(s). Then you can select whether the modulation effect occurs before or after the other pedal(s). This is selectable per preset.
