Hi Carlos,
What I've noticed when using the Axe is I have much more tone control (before using an amp sim) than when using the usual audio interfaces (which are thin sounding). The Axe was "fuller" in tone and once you put it through an amp sim, it was 'almost" like playing through a real amp. So yeah, I'm EXTREMELY happy with it.
Of course, there are much better products out there (i.e. Fractal Audio's Axe Fx, Kemper etc..), but at a heavy cost. If I had the money, I'd get the Fractal' Axe FX . I've been playing guitar for about 30 years and still suck at it, but I truly love playing the guitar.
Best is to go to a music store and check it out before buying....your ears will be the final judge.
