I haven´t owned any of the modelled amps. Here in Brazil those amps are incredibly expensive, like 2 or 3 times the price theý´re sold in US. I own a Fender Hot Rod Deville 212, and I can say that the Fender amps modelled have lots of similarities withe the real deal, and, more important, a really great sound. For example, if you use a drive/dist pedal, like Suhr Riot, which I own, the result you get inside the software is very close to the result you get in the Fender. However, I do lots of comparison with amp samples (on Youtube, official amp makers websites, etc), and the result is awesome. The last comparison I made was the Engl models, which sound amazing on Bias Fx. I think that a less trained ear can´t tell the difference between the real amp and the model.
