I recorded a piece using two different setups simultaneously.
I'll just post them first, without revealing the equipment.
I thought it might be fun, as has been done in the past, to
take comments on what equipment, procedures, instrument, piece,
setting, etc. was used.

In the end, I will reveal what three often discussed
pieces of equipment were involved.

Nope, can't hear a difference - they are very, very similar. I can see
some differences on my DAW, but that really doesn't count.

OK, that'll teach me not to listen from 45 degrees off my speakers'
axes, half buried in a settee. Not treble, perhaps, but the upper mids
are much brighter in No. 1.

Yes, number 2 is muffled by comparison but I was thinking more
of the unacceptable noise level in number 2.

Not required.

Yes, prominent even. Imo version two is best, assuming the intent is
that a recording of a guitar should sound like one.

One explanation of the tonal difference could be that 1 is recorded with
cardioids and 2 with omnis in approximately the same distance and
position. What also suggest cardiods is that the bass range in 1 is
wrong, just wrong, sounds like plastic.

1 may however work best in a mix, as just a recording of the instrument,
2 is the obvious winner.

The instrument sounds probable in that one, it does not so so in 1.

To me both sound a bit overly fat. I find both pretty similar, besides
the obvious loud noise in the second one. Maybe the second sounds a bit
more natural, but I find it hard to compare given the noise.

The most obvious technical difference is the vastly raised noise floor below
70 Hz on tester1. Overall spectral balance is pretty similar.

There's a 0.3 dB overall-level difference, and a 0.1 dB channel balance
difference.

Even with the level differences corrected, they easily ABX as being
significantly different.

The big sonic difference for me was soundstaging. tester1 has a strong
central image while tester 2 is more diffused.

Mt first guess would be tester1 is coincident-miced and tester2 is miced
with non-coincident mics.

The difference in the noise floor below 70 Hz may be due to the lack of bass
coherence inherent with spaced mics, or it might be something else.

I agree. I mistakenly transposed the names. Agreed that tester2 has more
noise.

I went in and measured the size of L-R for the two files:

tester1 L-R has an average amplitude of -35 dB

tester2 L-R has an average amplitude of -29 dB

As I said, while both files have well-developed L+R information, tester2 has
far more L-R information.

Both are so unnaturally "thick" that I can hear the quantitative differences
in the rest of the spectrum, but I cannot make a judgement as to the
qualitative differences. Neither is acceptable.

Both sounded very boomy or boxy to me. Much too much mid bass. I
added a 15 dB notch at about 200 H Q=1.5 and it sounds better.

I don't think that boomyness is from any electronics or mic but
probably from mic placement relative to the instrument.

I agree - too much box tone, the question however was about the
qualities, if any, of the technology used, not about the mic positioning
technique. Example 2 sounds like a wooden guitar and example 1 like a
plastic guitar.

This is something that I have known about my present guitar
since I have owned it. There is a troublesome resonance at
just over 200 Hz. When recording, I see the meters jump
wildly when I play the A on the third string. I have a feeling
that most of the negative comments on the sound are due to
this, #1 getting most of the blame because it more accurately
portrays the unfortunate character of the instrument.

So, #1 was a pair of NT1-A's into a Tascam HD-P2. The mics
were placed side by side, about a half-inch apart, pointed
in toward each other 30 to 45 degrees.

#2 was the front pair of elements on a Zoom H2. Both mic
pairs were about a foot and a half away from the guitar,
more or less pointed near the sound hole. That might explain
the boominess as well - I know that people recommend pointing
at the twelfth fret.

I was just sitting on a couch in a small room with the equipment
on a coffee table in front of me.

It's interesting that the #2 recording was preferred by many
as being more natural. I found it to be lifeless, lacking
detail, muffled, and terribly noisy. Unless I can think of
a use for it, the H2 will be seen on ebay soon.

As for the NT1-A's and the Tascam, I think that both were
worth the money spent on them. The #1 recording is representative
of what I was hearing during the performance. Both sound
quite transparent to me, which is all I ask of any audio
equipment. I think that I will have to look at the guitar,
and perhaps my right-hand technique in order to achieve a
more pleasing recording, although I'm actually happy with
the results.

I wonder if some sort of dampening might be used in order to
cut the ~210Hz peak that my guitar exhibits.

Both of those are interesting observations. I had an H2 around here
for a few days and, although I never would have guessed that it was
what recorded one of your examples, I thought it was "just OK" when
recording my guitar, but pretty decent on banjo. But in either case,
there was a fair amount of "room" in the recording.

I certainly wouldn't use the H2 as a serious recording microphone for
either guitar close up or concert from a distance, but it's fine for
practice, writing, or interviews. I didn't have a chance to try it in
a living room jam session, but I suspect that it would do OK for that
task - not to make a recording that I'd want to listen to over and
over and cherish, but to learn a tune or remind me of a fun time. You
don't buy a recorder like that for how good its mics are, you buy it
for how handy it is.

Yeah, in reality I will probably keep it around. If you think of
it as a voice recorder on steroids, it could have some useful applications.
It has a feature that allows it to record only when there is some
threshold of sound around. That could be useful in a few different
contexts.

I knew that it wasn't going to replace the HD-P2, but I am
still disappointed with the noise level, and slightly less
disappointed with the reproduction quality. I think it
was marketed far too heavily as a recorder that could be
used to capture music performances, although I do think
it would be great for a garage rock band; the noise
level would not be a problem.

That's marketing for you.
But what else would you say, if you were trying to market it?
Anyway, many live performances are louder than a single acoustic guitar
and wouldn't present a noise problem.

Coincident pair, more or less.

I'm surprised that they sounded (and measured) so much like they were
non-coincident.

H2's can't be used with external mics?

A rather signficiant size and cost difference - like 7:1?

That would be from the performer's viewpoint?

Sure - stereo mini jack with plug-in-power if you want it, or switch
it off if you don't. But if you want to use it with a pair of KM84s,
you'd probably want to BYOP and that defeats the notion of a
"Handy" (what the H stands for) recorder.

I was thinking that this would be something that I'd carry in my banjo
case at a music camp, or even in a pocket. If I want to record some
tunes at a jam session, I don't have to be "that guy with all the
wires and electronic stuff." I'd rather be just like everyone else who
set out their Zooms and Edirols and M-Audios (and there's always
someone with a gold plated Tu-Ba-Phone and a Sony PCM-D1).

I'd be willing to bet you didn't use the low-cut on the H2. Try it,
it will make a difference.

I'm afraid that you would lose your bet. I didn't actually intend
to turn the low-cut on, but I forgot to turn it off after recording
some speech. The low-cut starts rolling off at 100Hz. Now, normally
I should think that this would be a mistake, in that the fundamental
of the low E string on the guitar is ~82Hz, however, I had a capo
at the third fret (for lute tuning) so the low fundamental was
~98Hz. The low-cut is probably not a threat here. I suppose in
this case, the low-cut would simply serve to cut some of the noise
of trucks driving around my neighborhood. Any more thoughts?

Yeah, I've been able to identify it in any recording that I have

have owned the guitar. In fact, I can hear it just by playing

I would very much expect unnatural response from any acoustic guitar
in the 150 to 250Hz range given the mic placement Tobiah indicated.
For a near-coincident (side by side) placement, I'd angle them
outward, not inward, at much closer to 90 degrees, & pulled back to
around 3 feet.

A guitar is a mini room so it's going to have modes. Those problem
frequencies are likely the modes of the guitar. You just have to
compensate with mic position and equalization if the guitar has bad
mode problems.
