Zoom tends to do better with some effects than others. What I'd do is start adding individual pedals for those effects Zoom is weakest in. Order the real bass muff pedal from Guitar Center and compare. If you don't like it appreciably better, return it. The same goes for your other effects. Although I tend to think Zoom does great for chorus, flanger, reverb, and that sort of thing. Personally, I have a MS60B that I use in the effects loop of my Tech 21 VT Deluxe. Zoom can't touch the VT for distortion or amp sims, but it's great for the previously mentioned effects. Although I have a B3N, I prefer my VT - MS60B setup for live. The B3N is an amazing practice tool though.
