I know that turning the axe on and just playing is very error prone cause ears work unreliably from day to day, but I swear I felt the same way after using this firmware too. It felt like it got a LOT less raw and more "polite" for lack of better words. It's strange, maybe it's me, I'll try again tomorrow and see if I feel the same way. I wish I had recordings but I mostly use the Axe for live and practice.
Sanity check...
I was playing the beta for 30 minutes today before I loaded the FW. It was exact.
Check your settings. The wee knobs in the amp block will get you every time.
