GOOD: it's well-built, worked out of the box, and has a vast array of different effects. BAD: the "large hall" reverb wasn't as good as the cheaper Behringer FEX800 I purchased previously @ amazon.

I had a specific problem with the FEX800 -- it went weird on a single pedal Eb in a virtual theater organ! -- which I hoped a "better" unit would cure. Sadly the MX200 was not that unit. I suspect the supplied effects are intended for live pop performance, and while I *am* alive when I play in my living room, I would guess large "cathedral" reverbs are not at the top of the pop list today. ... I tinkered with the controls for an hour or more, and couldn't get a "big" reverb as good as the FEX800, let alone better. I could get a long-enough decay time with the MX200, but only, apparently, at the cost of unacceptable muddiness, particularly in the bass, which is exactly where I was seeking clarity!

So I'm sending it back. I gave it three stars because the only thing I *know* isn't good is the big reverb; if that's not your thing, then it might be the machine for you. But note that Amazon says they could charge me $10 for returning it just because it doesn't do what I innocently thought it would -- which is OK, but that policy doesn't encourage try-outs....
