Heh 2112 is not me ... that is Leon Todd - a local legend in these parts!
There is a bit to learn, and it can take some time to get your head around some of the concepts(I'd suggest concentrating on how Presets, Scenes, Blocks and Chanels work). Once you do though you'll love it. I read the manual countless times before my unit turned up (and borrowed one from a mate for a while), so I had a slightly warm start.
Here are a few of my MVP videos from my playlist (of other people's content!), and there are plenty of folks around here that will help you.
Most (Fractal) concepts are easily transferrable between the FM3, the FM9 and the Axe FX 3. Also, all units are very sensetive to the guitar you use and the listening method (eg headphones, monitor speakers, PA system, guitar amp). It is very important to set the unit up correctly for your usage method, so check out the FM9 basics. A setup for a PA or monitor speakers will be quite different to plugging the FM3 into the front of your amp.
