I know I'm extremely late on the topic, but I wanted to add my two cent for any newcomers that may stumble across this thread like I just did.
From my personal experience, I don't see why the Zoom H2n gets all the hate it does when using the internal mics.
Maybe it's because I listen to/record classic rock gigs, as opposed to the metal gigs mentioned by the original poster.
I've only recorded one gig so far, and it came out great.
There is also another recorder in the area that is on DIME and about 90% of his uploads rival soundboard quality with plenty of bass/low end.
Are people just not checking/adjusting the recording levels as soon as the show starts, resulting in brickwalled captures?
Now, I have heard a decent amount of subpar recordings with the Zoom H2...
