The protective packaging is certainly worth paying a little extra for.
Looking for electret capsule manufacturer recommendations

I ordered the Kingkorg electret capsule a long time ago for very little money and today installed it on a Sela T12 tube microphone clone as a test.
I am thrilled, that is the best ultra low budget capsule I have heard so far.
I will reorder a few more of them and also some KK version 2 electrets capsules(without front mesh) It's really amazing how well these capsules perform for the money.

Did I just get a capsule named after me?!?! Thank you for that
I had a synth made after me, but not a capsule.
Kidding aside, i'm glad you like it. The construction on these seem to be inspired by some of the CK12 models.

Yeah, is named after you to honor your original reference to these bargains. The KK12 exists in 2 versions so far in my world.Did I just get a capsule named after me?!?! Thank you for that

Now I'm on the hunt for matching 25mm capsule holders. So far I've only found one on Amazon, but costs more than double as the capsule. Scandalous!

FWIW, on mine I cut the plastic BM700/800 capsule holders down to a saddle-like shape, mount them on top of rubber grommets, then affix the capsule with Scotchmount Extreme mounting tape, which being rubbery, also provides additional vibration isolation.

Yes, thats a good idea to buy donor mics for small money. Holder and body, all I need in one package. That mounting tape looks good.
Recording Tools got nice and cheap 34mm capsule holder. Maybe I can modifie them...

Look what I found, has been lying around here forever. Some green spray paint and voilà my mini C12 is ready to go.

Good Idea!
@KK: It is possible to make a sheet with the response of the old and the new capsule in one diagram?
Look at this:

That's food for an 3d printer.
Just use 2 Rubber 0-Rings on each mounting hole, one ring above, one below and screw in the mounting screw w/o really fastening it. Use some Locktite on the threads...
Just gluing them to something isn't really a good idea in my eyes...
Regards,
Holm

Thanks a lot Holm.

Today I received 4x "KK12"s capsules, I'm curious how V2 sounds compared to V1.
Amazing that the capsules have survived the trip at least visually. They were completely unprotected.

V2 is slimer than V1. 7,8mm vs. 10,5mm.
Diameter is the same.

What are your thoughts on the differences and which one would you recommend?
The thinner one is smoother, less HF boost, but slight low end roll off. I don't really care, not much LF variation and character in condensers anyways, so you can just boost what it lacks. However at some distance it might sound thinner because of this. It has good rear rejection.
The thicker one maybe tiny bit scooped sounding, really large bottom upclose, and more, but not too much HF boost. It's hypercardioid, so less rejection from the rear, more from the sides, hence more proximity effect.
I love both for handheld condensers, or close miking stuff. They sound huge used like this. Great improvement over that poor TSB165a which used to be staple for low end condensers.
IIRC the thicker one has spot on Slate ML1 response when put in flat circuit.
For the price these two will never be beaten i believe.

Essentially what KK has already written. My assessment depends strongly on the intended use. For longer distances, I prefer the V1, the thicker one. It also depends on the headamp. In conjunction with a vintage tube circuit ala Sela T12 I also like the V1 better, with a more modern FET circuit I would rather prefer V2.
My clear recommendation is, buy both and try it out for your intended use, used mic technique and taste. Very good price-performance ratio!

After using my sm58, I would prefer something something with abut more HF detail. The thicker sounds like it has the profile of an sm58?
You mentioned rear and side rejection. As I will be using a desktop mic, there will be sound coming from the rear (speakers) and side (keyboard). I can't tell which capsule pattern is best suited for my use case.
Leaning toward the thinner one based on what you two have said.
Both will give you substantially more low end and detail. Cardioid vs HyperCardioid will depend on where the speakers are placed.
You can go for amazing trick not many know about. Put the mic dead center between the speakers. Put mono signal to both speakers, and flip the phase on one of the speakers. This will give you most cancellation and lowest level comming from the speakers dead center where the mic is, but your ears will still be able to pick up the sound as usual, but with less low end. This is the trick used by engineers where vocalists don't want to record with headphones. I believe Black Hole Sun is recorded this way.
Hypercardioid would be the best choice in this situation.

That's a very interesting trick. I tried to google about phase cancellation and most audio engineers try to remove it and not introduce it
. This was the only video I found find demonstrating the trick, the results don't see too impressive though.This a model of my room, I have a desk in the corner that meets a sloped ceiling. Unlike a studio setup where the speaker is away from the desk, my speakers are set on a desk. In my case, I feel like a cardioid will be the most appropriate?
Could you elaborate on that? My impression has been that condensers often have less LF rolloff than handheld vocal-oriented dynamics (and better HF extension too).
Either way it seems like there's not much information in the bass (the bandwidth is narrower) and you ought to be able to EQ it better than the HF, because boosting HF exacerbates any circuit hiss.
Am I wrong? Is there LF circuit noise (rumble?) that's a problem that limits your ability to boost the bass with EQ? I would think that LF rumble is usually ambient noise, e.g. from trucks driving nearby or room mode boom, not a mic issue per ser (unless you have a bad shock mount), so it's going to have the same ratio to LF signal whether it's boosted or not. (Boosting a weak LF signal will also boost any LF noise, but won't change the ratio.)
Of course if there's really no LF signal, boosting it won't help, but I'd think a difference of a few dB where the bass rolls off would usually not be an issue.
