i heard some pretty nice demos on you tube..includeing halen n' may. just search 'you tube nux mg 300 rock'.
this bloke does a pretty interesting intro to the unit.
https://www.youtube.com/watch?v=tal_L_5STP4still tho' with this unit you can get 'fuzzies' if thats what you want. but not for moi.
my conclusion is some pretty nice rock tones just sitting in the pocket good as well as clean tones.
might even be able to get marvin tones on it.
i'm still on the fence. gonna do more research.
