I gigged with mine the first day I got it. Programmed five patches in 30 minutes (without prior knowledge as to how to use the editing software) and took it with me (Twin for cleans, Plexi for dirt). Admittedly it was an easy gig compared to many - I'm a worship player, so just 6 songs (though we did two services). I could not stop grinning for weeks. My first efforts were primitive but it sounded WAY better than the HD500 I used to years.
Still, I can understand the hesitation and admit I was being obsessive. What got me (and still does) is how easy it is to make great sounds and how hard it is to make them suck.
After almost 50 years of playing, touring, sessions, and spending a fortune on gear (had a good job), Fractal is by far the best money I've ever spent. I just finally added an AX8 to the arsenal and marvel that something so small and "simple" can sound identical to a $3,000+ rig.
