I got the email yesterday to upgrade my firmware to 2.0. I have not done it yet on the amp and am not near it at the moment but will be doing the upgrade this weekend to see what, if anything has changed. It says new effects and new presets and that is all. What I don't know yet is how it will change the existing presets, or if it will. I like some of the factory presets a lot, so I am hoping the old ones do not change. I will let you know what I find after I have upgraded.
