Here is a video I did comparing the Mesa Boogie Dual Rectifier (Red Channel) vs the Pod HD Pro X Treadplate model.
I just did this as a comparison video just to see how close I could get the Pod to sound like the Rectifier using only the effects, amps, and cabs available in the Pod.
They are somewhat similar, but I like both the sounds and would have no problem using either one on a recording.
