First impressions...
1. The damn thing is just cute. Not a word I normally use, but I can't think of anything else to describe it
(and I'm trying not to use the words "form factor").
2. That's Our Boss(TM). Those of you describing that Boss tone aren't wrong -- it's definitely there.
Not nearly as bad as the COSM stuff, but even my first experience with the X amps was meh...
Fractal's amp modeling is just clearly superior; the FM9 has spoiled me.
I noticed LT was using hi/lo cuts; I'll be trying that. And to be fair, I haven't tried dialing in any of the amps yet.
3. Pretty decent array of presets; I tended to like the cleaner ambient stuff (esp. on the neck pup of my tele deluxe).
Some of the FX-heavy ones were inspiring. And some of the presets are surprisingly complex.
4. The acoustic sim seems noticeably better; that might turn out to be a pleasant surprise...
5. Had read the manual, but the thing seemed pretty intuitive almost immediately. I like that while it has
a touchscreen, you aren't forced to use it.
For me, an awesome upgrade to the GT-1.
But it's no FM0.
