Q: Do I need to reprogram my changes with the Mission Expression Pedal every time I plug the pedal in?

A: You do not need to restart your effect unit every time you want to reset the expression pedal. Your expression pedal settings will remain the way you set them up regardless of effect knob settings. Your expression pedal settings can be saved to the effects parameters saved by the footswitches.


Q: Can I use the Mission Expression Pedal to control the volume, wah, or tweak function on my Line 6 product?

A: Yes. Simply plug the Mission Expression Pedal into either the "PEDAL 1" jack or the "EXPRESSION PEDAL" jack on the back of the device.


Q: How do I use the Mission Expression Pedal with a POD unit when connected to the unit or an FBV shortboard?

A: Press the "Edit" button, then turn the "Select" knob until you see the "Wah/Volume" page. On the Volume side, select or highlight "Assign" with the third soft button located under the main display. Turn the "Effect Tweak" knob to change from Volume to Tweak. In the PODxt, these parameters are changed on the page after the "Wah/Volume" page. By changing from "Volume" to "Tweak", you have engaged the Mission pedal to control any function that comes under "Tweak". To find out what's under the "Tweak" selection, turn the "Select" knob to the next page where you will see "FX Tweak | Tempo". On the FX tweak side, you may scroll through the stomp tweaks, delay tweaks, mod tweaks etc. Make sure if you select, say, the delay time, the delay button light must be on and so on with the other effects types.


Q: How do I use a Mission Expression Pedal with a Stomp Box Modeling Pedal?

A: See the following document for information on how to use the Mission Expression Pedal with your Four button modeling pedal:
