Ok so I just got a POD X3 Live, and I absolutely love it. The diversity, the possibilities, it's great. But one thing I've noticed is there is a Pedal 2, and I can't seem to find any info on what I can put in there (I think an expression pedal?). Also then what will that control (and how can I configure it?). And finally, can I just use any expression pedal?

Help would be greatly appreciated

Check line6 on the net, they sell the pedals you can hook to your x3. I have a Boss FV60 volume pedal that works just as well. How to configure is in the manual.
