FC6 is a great form factor. For playing with a band that has consistent predictable changes in each song (I use a preset per song with scenes for different parts), it is perfect. However, for using a versatile kitchen sink approach, improv playing and jamming, I feel like the 6 button interface is too fiddly for me, at least for now. This probably wouldn’t be as much of an issue if I was focused on just guitar, but when I’m singing as well, and trying to connect with the audience, I just want more things on tap without hold functions and menu navigating. For these reasons I may pick up the 12 when my invite rolls in, even though I really like the 6, which is more capable than I first imagined. Hope some of this helps.
