Hello!
Does the FM3 sound differ from the Ax FX2 Ares 2.0 firmware?
Does it make sense to replace the Ax FX2 with FM3?
Thanks!
Yes. But think about this:
Axe FX 2 sounds pretty much like a real amp and people fail miserably in Blind tests.
FM3 sounds pretty much like a real amp and people fail miserably in Blind tests.
If A sounds like C and B sounds like C, it logically follows that A sounds like B.
In other words, there isn't a world of difference between Axe FX 2 and Axe FX 3/FM3.
Still, there are differences, and if fractal dudes aren't lying, the FM is more accurate to the real thing, of course, but it's something that you would hear only by A/B switching them and listening closely. When casually listening to music, you would never go like "Hey, this sounds more like FM3 than Axe FX 2".
Axe FX 2 sounds great. FM3 sounds great. Different shades of great. Does accuracy matter to you or is sounding great all that matters? Didn't Amp modelling reach a point of "Just another tone", and it's just a matter of taste for which is better?
Anyway, when considering the differences between Axe FX 2 vs FM3, there are a lot of other things to consider.
How I see it, is that the FM3 beats the Axe FX 2 in pretty much everything, except for the number of instances of blocks.
Do you need that many blocks? I don't.
If your stage rig is rack-based, Axe FX 2 can be convenient, especially considering that you can connect multiple guitars to it... uncomfortably, but you can..
Otherwise, I see no reason to go Axe FX 2 over FM3. It's a valuable upgrade.
