Yeah, I guess Alice in chains isn’t such a great example of “simple” progressions. I was referring more to punk than grunge. But I see what you are saying about them focusing more on emotion than technical prowess. Which would be understandable for me why I am not so into that, since I never really play live, so emotion is quite a non-factor for me. I therefore focus more on technique, and the 70’s and 80’s in particular are a goldmine for wonderful musical technique. (Rush, Sabbath, King Crimson,..)
About the case, I particularly want a softshell because I need something I can fold up and put into a small space. I have a hardshell and it’s not so practical for me right now.
Good luck on deciding about a new amp!
