This is the real deal. I've owned a whole bunch of amp simulating pedals over the last 15 years, they've been getting gradually better over time but never sounded passable UNTIL NOW. God bless you modern science. This pedal sounds (and behaves) like a great amp (and actually it has the added option of speaker simulation off so you can get a more direct sound than an amp can offer). In my opinion, the old stage technique of 'have the amp backstage mic'd' is obsolete thanks to this pedal.
