.. the Great River MP-4M and the MP-2NV soundwise?

I had the 2NV and plan on getting it back, unless the MP4M is as good. I'd love to have 4 channels of that.

Did you love the NV & set it free? it should come back! heh

So does that mean I should get the 2NV instead of the 4m

It wasn't so much "set it free". More like hired to tour with a band and lost my ass off in a big freakin way and am now having to start over with all my gear.

As far as I know (I don't own them), they are different. The 2NV is a versatile mic pre based on the neve 1073 being able of getting cleaner than the 1073 or colourful. And the MP-4 is a "clean-transparent-reference” family mic pre preferred for acoustic instruments recording.

ditto

I've got an MP2M and I love it. It's clean and big but not boring at all. I've never met a guitar sound, acoustic or electric that didn't benefit from the GR MP2H. The MP4H is the same, only double.

You sure about that???

I don't think thats right either, thats why I asked. I think I most likely will get the 2 though.

Careful, DC11. You didn’t ask that. I suppose you confuse the models.

You asked about “4M” vs. “2NV” and not “2MH” vs. “4MH” or “4M”

I don’t remember exactly but there is a minor difference between the “MH” model and the “M” model being both of them basically the same concept, while the “NV” models are a different concept. There’s no 4 pre box of NV’s.
In the NV family (neve-ish) there are 1 pre and 2 pres boxes.
In the MH family (clean, transparent type) there are 2 pres and 4 pres boxes.

Have a look by yourself:

Mine is the MP2MH with the transformer and two different outputs. I only use the XLR/transformer out. I didn't realize until TapeOpCon when I was talking to Dan Kennedy that the two outs were different. The 1/4 out is transformerless. I need to try it someday.

Anyhoo I’m sure an MP4MH would kick ass because the MP2Mh does!

Just to keep people guessing I use goofy model numbers.

The 2MH and 4MH are identical only twice as many channels. the 4M is the same as
a 4MH less the unbalanced outputs.

The NV series is a whole different beast, with roots in the old '70's "ring of three" transistor topology instead of a high speed discrete opamp. Not a 990, or 2520, or an AM-10, but a discrete opamp of my design.

They sound different, but have some similarities because of the way I do stuff, which is mostly they both have great imaging and low noise. But the NV is definitely the "rockier" of the two styles.
