I finally got to mess a few minutes with the new improved ac30tb in the new fw and man, it's like night and day!!! I'm not 100% there yet, but now I feel I can get there much easier (and mostly it does sound great in most settings like a real ac30) as opposed to previous firmwares where I was constantly unhappy unless using 2 amp blocks. So thumbs up for @fas for listening to customers' feedback and putting it into the unit, thanks so much!
Anyways, sloppy recording, full U2 live track on the left, my guitar on the right, guitar track was much louder than backing track so I got lost here and there, but hey, after all this test was for tone, not for skills!! lol
