ok, this may help with Line6 setup:
Start with the volume setting and plug in an expression pedal and make sure you that the Toe/Heel set up to bring the volume from 0 to full on. Once you know that is setup working then switch over to the HH3 and experiment with the settings on HH3 receive and waving the HH around until you find it working like the expression pedal was. Turn the HH ring around if you still can't get it to work. And remember when you 'calibrate' the HH you are setting it's center position.
Hope that helps. I've spent hours dialing in what I've shown in that video, so don't give up. It's worth the effort once you hit that AH-HA moment.
