Perhaps this is a little obvious at least from my perspective, but what is the point of updating the firmware if you just want to use the older version? The whole point of upgrading the firmware is to have a much more accurate and powerful device that will sound better. I can understand that people like their older version of their presets, and by upgrading firmware they might have to tweak the settings a bit. To me the individuality of a guitar players tone comes from their own fingers and their own unique technique and skill. Having a much more powerful device to bring the sound you hear in your head to life is what every guitar player really wants. Which is why you have people like Joe Satriani, Steve Vai, John Petrucci, etc,. using this monster. I think like any product you have to decide whether or not you need to upgrade to the next newest firmware, and whether or not it would be a benefit for you to do so.
This is just my opinion in my circumstance, because the whole reason I purchased an Axe Fx II XL was because of what it can do.
