I've made a Mooer Preamp Live work as a backup with its 4 buttons (presets) and two "scenes" per button, but that's hardly the point.
Anyone willing can "get by" with three, or even two buttons. Hell, I can get by with ANY amp and the guitar's volume knob, in a pinch.
But then, what's the point on having 256 amps, 8 scenes and a bazillion cabinets at your disposal?
I don't like modularity in the same way I don't like DLCs in games, cars where everything is an option or phones with shit apps where I have to purchase the quality ones.
The FM3 is NOT a subtitute for the AX8. FM3+FC6? Maybe, but that defeats the small footprint, the price and the simplicity.
Nope, thanks.
