The main problem is the price of the unit, it's too cheap! People who post to guitar forums who have never seen the unit, read guitar cork-sniffer monthly or will argue about NOS tubes all day will never buy one because it's not $1500! The other issue is Zoom don't have any high profile endorsers or brand champions. I think the unit is fabulous! When I got mine, I saw it as a 'toe in the water' path to a Helix. Now I have dialed in the Zoom I am not so sure! I love it! It's the best thing I have got in years! My gigging rig is tiny and the tones are first class! Like you say, maybe a Helix is 'better', but $1200 better? Probably not!
