I been a gigging musician for more than 30 years. I have owned a ton of amps. I have owned several Fractals, Hotone Ampero, Headrush and Roctron Prophesy. I currently have the Fractal Axe FX FM3. I have downloaded and been disappointed by so many patches I've lost count over the years on the various modelers I've owned. Not these! Right out of the box they are ridiculously good! All I did was add an in/out block and pick an included cab IR which are also ridiculously good. I use these IR's for everything now because its always an improvement!! These patches cover ANY heavy tones I might need. I'm told that there will be some mid gain and clean patches in the future. Can't wait for those to be released.
