Hi, I have the PodX3 bean version.
There is endless capabilities with them. You get the device as well as software that allows you to tweak until you can't tweak anymore.

Having said that, I prefer (up to this point) stand alone pedals. For one thing, I like to mod my pedals. Not going to be as easy if even possible with a POD.

I'm actually digging into my POD manual a bit more over the last day or two. I know I can get even better tones if I try.
