Since 19.05 I felt like I was the only one not happy with the new firmware until now. I've only been using the Axe III thru my Atomic CLR's at home. But 19.05 just wasn't right (for me).
I've made many presets (40) I keep it simple (amp - cab - dash of reverb) I'll use a variety of amps and guitars depending on my mood or needs.
But after going from 19.02 (which was great) to 19.05... everything changed tonally, even feel wise.
Best I can explain it is... my tones lost something. Grit, grind, bounce, dynamics. looseness, life, and feel. Basically, some of the terms we use to describe most tube amps. I remember seeing the words "smoother distortion" and "clarity" in the release notes.
I ignored these words and installed the firmware. I played different guitars, used different presets... it was everywhere. Again... playing at bedroom levels (I turned up a bit).. still there. My son confirmed what I heard. I reverted back, and everything was great again.
IMO, tube amps generally aren't smooth... tonally, or feel wise. It WAS great in 19.02... not in 19.05.
Most have said everything is awesome (as usual... and it usually is) but (for me) not this time, and not in one or two sounds. It's not something to 'fix' by adjusting some eq (as an example). But, not many are mentioning this regarding the last firmware. It cannot just be me.
