In my opinion, it's the best multi effects unit. I love how it's set up like stomp boxes lined up next to each other. editing the sound you want is very easy, and quick to figure it out. I love that you can plug it directly into a PA system as well. the effects sound authentic and there are more sounds than most players would ever dream of using, and you can save 100 patches of your own designs. It's compact enough to not be a burden to carry around, and it runs on a plug or batteries. the only thing that I'd like improved on is being able to scroll through the effects faster, or have them split into seperate menus. Besides that small detail, great product. I love using it and owning it.
