the fender vibro champ xd - is a 5 watt tube amp, it has a bunch of modeling presets and some basic digital effects.
the effects are very limited because the all share one dial, so you can't mix them.
however it sounds real good at low volumes, and takes pedals well. it has a line out the can be run to a pa or high power amp
if you need to play out somewhere and need more volume.
if you want something really cool buy 2 and place them as far apart as possible and run stereo out of your pod to each one.
you of coarse can do this with any amps, as long a you buy a pair.
