Will do a comparison of the GZ74 along with a few other SDC mics I have. I couldn't get the GZ74 in the right spot to included it in the group above.

Gotcha. That will be great. We haven't heard much out of the 3U SDC's.

damn, that 47FET V is really cool sounding, I'm def going to get one. its got all the detail of the rest and had a very professional sounding smooth top end.

the GZ251 demos sound very good too - quite thick and in the foreground.

Only other mic thats exciting me is AEG/RTT's 19a9 replica tube mic - not sure which to buy first.

FWIW: Just heard back from Guosheng that GZ74 is out of stock now.

is anyone noticing something different about the GZ251fet? it sounds slightly more narrow but really punchy in a good way?

The differences between the mics are definitely more pronounced on your vocal clips than on your guitar clips. I think that might have to do with the guitar, it sounds like it hasnt opened up yet or a little overly jangly; seems to be a little more pronounced on one side of the frequency "spectrum". That might be a trait of an all koa acoustic though, i dont know I havent played or recorded one. Try moving the mic down from the 12th fret towards where the neck meets the body, and play with it there maybe more soundhole then neck or the other way around. I would also suggest maybe bringing the mics closer to the guitar like half of what you got goin right now. That might help the guitar out and make the differences shine even more.

I know everyone on here shouts the mantra "treat your room" but just because a room is treated doesnt mean it sounds good or the room sound your mic is picking up in said treated room is good or flattering to what people want to do soundwise. So dont be shy to experiment with throwing up a blanket behind the mic stand or something...just play around with it and see what you like better.
The vocals i liked either the 47fet V which sounded a little more vintage and smokey or the 67fet which I think would sound real nice also; i really like her voice.

Side note Im not sure I like the reverb it seems to be doing something phasey and weird with the instruments and vocals.

Definitely looking forward to hearing those sdc's Im jealous!

The guitar is a 12-fret so the 12th fret is where the neck meets the body. If I were not testing several mics at once I would not have been so far away from the mics. I need to test each mic separately with the closer mic positioning and forget about the single pass thing, since it doesn't seem very useful for acoustic guitar. The guitar sounded incredibly boomy which is why I put the filter on. I think mic'd closer it wouldn't sound so boomy. In the room the guitar is not boomy at all.

There IS something special about that GZ47fet V, at least on her voice. That is my favorite 3U Audio mic.

I have been traveling with my job and trying to buy a house, both of which keep me away from my studio, so I haven't been able to get out sound samples as quickly as I'd like. I'll redo the LDC samples for acoustic guitar this week-end (since the mics are still on the stands). Hopefully I can get to the SDC samples too.

Here's a track I recorded (acoustic guitars and vocals) exclusively using the Warbler IV.

Nice!...love the retro vibes!

Awesome music! Nicely done!

Just two weeks and a MKII D is hopefully arrived here :D

Where can you order these mics? Is it only from ebay?

To get the early adopter price, email 3U mic designer Guosheng Zhuang directly at [email protected]. Since he saves 10% not having to pay Ebay's fees, he passes that onto the consumer. Plus, he's a super nice dude and will patiently answer your questions.

Thank you!

Very nice hognogger!! Which position on W-IV for acoustic and voice?

Really nice and unique. Great work.

Could anyone recommend a matched pair (which model) of these Mics which would give me a U67-ish sound and vibe? Thanks.

Has anyone used the GZ67?

TapeDub, This is the demo thread for the microphones and I have found that there is LOTS more discussion about these mics in the initial thread that was started by KidVybes, https://www.gearslutz.com/board/low-...-voicings.html.

I'd ask over there since you'll likely get more responses. I have the GZ67fet, and find it to be a good mic, but I have not compared it to a u67 so I can't tell you if they are similar. There are sound samples in this thread of the GZ67fet.

You've got the GZ67 as well as the GZ67Fet? I lose track.

I would love to hear a comparison between those two mics.

My mistake, I have the GZ67fet, not the tube version.

Ahh gotcha. I have the GZ67Fet too. A very nice mic.

Sweet!!

My previous clips of acoustic guitar with these mics were a one take with all the mics bunched together. You really couldn't tell the difference between the mics so I decided to record each mic separately to see if the differences would be more noticeable.

Setup: Apogee Quartet, Dynaudio BM5a
Guitar: Taylor GC 12-fret all Koa, pick .73 Ultex for strumming, fingers and finger nails for fingerstyle, Martin 12s Retro Strings
Mics: Had the filter on for all clips, had the -10db switch on for the strumming, cardioid pattern Warbler IV D on voice 1.
Placement: Pointed at 12th fret about 15" away.

GZ47fet V

Warbler IV D

The differences are still subtle and as I listened to each finger style clip I kept thinking, ok I like this one better than the other and then I'd go back to the other clip and think well maybe not. So it is still a toss up for acoustic guitar for these mics.

I don't like either of these mics for acoustic guitar because they don't sound detailed enough and while the top end is smooth on all of them, I don't like that for acoustic guitar. The GZ74 sounds better for acoustic guitar, but still a very smooth top end. I'm going to do my own personal shoot out with the Rode NTK (C12ish) and the Cascade Knucklehead (more mids) and see how they sound.

Finally got a chance to record acoustic guitar with the GZ74!! I recorded the GZ74 with a 12 Gauge Green12 since it is the only SDC mic I have.

I have the raw guitar clips and then clips with a high pass filter (100Hz, -12db).

Setup: Apogee Quartet, Dynaudio BM5a
Guitar: Taylor GC 12-fret all Koa, pick .73 Ultex for strumming, fingers and finger nails for fingerstyle, Martin 12s Retro Strings
Mics: GZ74 (cardioid) and 12 Gauge Green 12 (cardioid) adjusted input gain on the Quartet so the levels would match I had to use more gain on the GZ74 to get the mic gains equal, the gain was turned down for both mics for the strumming clips.
Placement: Pointed at 12th fret, 17" away

My first impressions were that the GZ74 sounded muddy, once I put the high pass filter on it sounded warm, but not muddy. Not as bright as Green12. The Green12 was ridiculously noisy in comparison to the GZ74, though I liked the brightness of it. If you hear the clips with the low pass filter the Green12 doesn't sound as big as the GZ74, but does sound clear. If the Green12 wasn't so noisy they would complement each other well.

Thanks for taking the time to make all the samples including the GZ74!

I can hear much more of a difference on this batch then the other. You can hear the difference between the gz67 and gz47 V in the way the highs and high mids sound. You can also hear the difference in the Warbler IV too. I would have prob liked to hear the comparison without the filter or pad on if it was for me. I much preferred the GZ74 to 12 gauge green in all samples...the green was not flattering at all and the highs were not good.

If it was me, and I say this appreciating your contributions greatly so please dont take this the wrong way at all (its the internet so I have to put that disclaimer out there haha)...I would sell that guitar ASAP and get a Martin (spruce/rosewood, spruce/mahogany), or a Gibson J45, or maybe a Harmony Sovereign H1260 that somebody x braced if you want to save money. I think you are going to see your greatest sonic improvement there. That koa guitar just has no nuance or body to it and it comes off as tinny and empty sounding. It might sound good live but it is not a recording guitar and if thats what you are going to be doing in the space you just set up, you got to remove it from the equation. I think you will get much better songs and sounds.

LOL... no offense taken... I probably should have chosen traditional woods to record the clips . I do have other guitars that I can record. Here is my arsenal...

Taylor GCce 12-fret SLTD (all koa) ~ 512ce 12-fret (cedar/mahogany) ~ 412ce SLTD (sitka/walnut/maple neck)
Martin Custom Shop 00-14 (all mahogany) ~ Dreadnought Jr (sitka/sapele)
Gibson Keb Mo (adirondack/mahogany)
Breedlove Northwest Classic (sitka/myrtle/maple neck) ~ Oregon Parlor LTD (all myrtle/maple neck)
Bedell Bellissima (sinker cedar/rosewood)

Thank you everyone for the recommendation on GZ47V and the next mic, I've few things to sell to fund this. Until then I only have GZ-251 and here is the latest recording. Please check it out.

Great track man and a great artist!

Am I missing something though? I've seen the studio recording video of that song and it looks like a neumann m147 ?

Edit: err tlm67 perhaps. I goofed

Busted!
