2 friends of mine already have 2, they said its dead on accurate. This is coming from professional engineers that have recorded some of the biggest bands in metal in the last 10 years. just do a search on youtube, theres GREAT videos of it. Theres one of a soldano SLO, a couple of rectifiers etc. They are quite unbelievable. What is really impressive is that you can then EQ the sound you profiled, thus being able to create tones that the original amp wouldn't even be capable of. What is really amazing is the low gain amps that I have heard profiled on youtube. They have the response and (supposively) the feel of the real amp, and sounds identical. You literally can not hear any differance. This will open up a whole new world to amp modeling for sure. Being able to share profiled amps online and download them on to the kemper etc....This should be incredible.
