For the few presets I checked, most of the cab IRs looked already aligned -- but will check them all with that new feature. I also love the new Cab Block shelving choice -- I will likely make the default always be the 12db/6db option (so harder slope on the bass cut-off shelving point). That will clean up some bottom end/tighter.
I'm getting a second Axe III (used!) so I can A/B the 2.05 firmware to the 3.x and will have that ability in the future. (Also can have one set for FC6 and another for FC12). Needed to do that, to really compare firmwares side by side to know (if anything) what to adjust, that's the most efficient way to do it - put on the Ditto looper and A/B box into each and tweak one to see if can get close to original.
That said, I do expect some sounds/tones will change in next update, not dramatically, but some. It's to be expected with major firmware changes (going from 2x to 3.x) - but the few presets I played under 3.x still sound pretty great... But if you love your tones now, you don't have to update firmware, that's okay too! If past is prologue, Cliff may have more updates and cool new stuff coming...
It's going to take a long time to do all of this RIGHT (especially with controllers now) for the next update, so I don't expect the next 1000+ Naked Amps TonePack update to be done until this summer (hey, I still have a 9 to 5 job and have to travel away from my studio mid-week sometimes), but we'll see. I also want to add some new presets/sounds too/expand it some. So be patient, the wait will be worth it!
If you have any thoughts or feedback, let me know. Remember, these Naked Amps are a tool for YOU to get YOUR favorite sounds and customize " the last mile" for your hands, your guitars, your ears.... I'm just trying to help you sample the amazing amp "smorgasbord" in this box, and save you lots of time and work -- so you can play more, program less...
Really appreciate all the kind and helpful feedback you all have given me since started all of this 18 months ago...my commitment to you remains to make the best amp tones I can! My next immediate priority is to finish work on a 250+ (or 500?!?) Bass Tonepack done for the AX8 (and then Axe-III version), and later XL and Mark II. Collaborating with bass guru Scott Nelson locally on this between his tours/gigs, and we are about 33% there...then the 1000+ Naked Amps for Axe-III update is the next priority, although I'm starting on it here and there!
