The guts are the new N series guts like the new B3n and Gn stuff that plays with the new Guitar LabI don't like carrying extra things around. If it's smaller and lighter I might get it just to get rid of the other pedals I don't use.
I'm not crazy at all about the sounds on the B3, but I'd use it if I didn't take up as much space as it does (I know its tiny, but not tiny enough for me). Are the guts in this new one essentially the same?
