Thanks for your feedback guys!
@kylotan - Initially I was pretty surprised that the Archon and the others sounded so alike as well. The Friedman/5150/Soldano thing I've noticed before in other amp sims as well, they just seem to share some basic tonal characteristics I suppose. The Revv and Mesa have their own identity in this mix I'd say, the Mesa's EQ is radically different and the Revv has twice the gain of the others for the same setting. The IR, however, is absolutely doing some heavy lifting here, and just goes to show how much of an impact it has. I originally shot it to basically get 'my sound' from the practice room to the studio, since I've been miking up cabinets with T75s for two decades, and most T75 IRs I heard didn't sound the way I wanted them to.
I agree with @Rocco_Crocco that the Mesa wasn't my favorite at all. I would consider using it with one of the others as a quad-track partner though, to fill in some of the gaps in the spectrum for instance. Or, say, with a crossover, Sadites-style. Also, I just plain forgot about the Line 6 amps in this shootout. The Epic is one of my go-to lead tone amps, but I have to give the Badonk more time. I hear people on Youtube all the time who are getting great tone out of it.
