I love being able to control HD500 parameters with my Variax tone and volume knob and look forward to doing it with Helix too. What I really want is to be able to control the Variax tone, volume and even tunings, models and pickups with the POD or Helix either with the expression pedal or with a foot switch. Using the exp pedal to control guitar volume has a totally different effect than changing amp volume or drive but for me its a PITA to get it consistently right. And being able to hit a FS to change tuning and guitar model or pickup would be amazing!
