1^st DIY Microphone Kits webstore since 2013

A friend of mine asked if I could build an M251 for him. Of course I said yes. I've built 13 M49 and two U67 clones.
I learned a lot from building this model. I will definitely be building more.
My friend is a known engineer and mastering engineer. He tried it out on himself and a well known female Nashville studio singer. She sang a pop song close to the mic , then an Italian opera song about 3 feet away. They both sounded amazing!
I love how Mic and Mod kept the **** look and sound of the original Telefunken ELA M251. You will not be disappointed!

I had the opportunity to record with an original M49 for about a year in my studio, and the M9 holds up very well next to it. Being my first mic to build, a little help from Ruud was needed, but it is a beautiful mic! I may end up building some for other friends as well!

Documentation was good and easy to follow, we choose the K47 capsule, good sound, we added epoxy clue to the sides of the tube socket board, into the metal frame grooves, to support the tube board better, when tubes are pulled out we dont want too much force to go into the solderings

Well, just did a long session with M47, Neumann M147 and WA 47.
The three mikes were placed on different spots, capturing the same source - a folk instrument, similar to flute, with lots of breathing and whistling sounds, in a "dead" room.
I definitely liked the M47 best of the three mikes. It was placed furthest from the source. Yes, the superior sound quality might have been due to the position, but M47 is definitely one **** of a mike! Absolutely killed the other two. Saving dough for another one.....

Beware... highly addictive... I have now built 10 M&M Mics DIY... and they have all been a great experience... This stereo set KM84 also sounds fantastic... looking forward to testing it on some acoustic guitar soon

Mechanically I found this kit to be a little harder to assemble than others. Also it is a little brighter than I expected. Works well on darker sources to brighten them up a bit. In general I am happy with the result.

The sound is very similar, it is difficult to tell the differences, which is very good. Maybe it's a little more presentable than the original, but I can't claim that. And my Neuman U87ai is 30 years old, if I put the original diaphragm from Neuman, it probably wouldn't be 100% the same..... great job, well done.

The M47 was packed extremely well, I was very pleased. The build was fairly easy, the instructions were very nice. The microphone looks and feels great. I have not used it in a recording yet, but left it on for a day, just to make sure I didn’t make mistakes with the assembly. I know quite much about it and am confident it will be a great asset to my studio. I have a dual channel Redd47 replica and Urei 1176, which paired with this beast will make the ultimate Abbey Road vocal chain!

I am planning to buy a pair of M87s, just waiting for the right time.

Thank you, Mic & Mod, job well done indeed !!!

ich habe es noch nicht testen können

ich habe es noch nicht fertig

Ich habe es noch nicht fertig

The with M7 capsule in the M9 kit sounds just perfect.

As a producer and sound engineer, I have owned and used every professional mic ever made for decades and know them well. U47's, U67¨s, U87's, TLM's, Telefunken's, C12's, Manleys, 414 vintage and XL's and the C800.

That said, I was on the fence wanting to buy this capsule for a couple of years.
I regret waiting so long, it would have saved me so many headaches.

I finally bought the K87 a month ago and installed it in a MA87.
It's a $70 dollar mic on Ebay.
I was blown how it made this cheap mic sound better than a $4,000 mic!
I can't believe how linear sounding it is.
When I boost the treble 2 - 3db it's crystal clear with no plosive harsh consonants.

The K87 is a great sounding capsule in my ears.
Makes mixing vocals a breeze, I barely have to use any eq or compression.
I will be replacing a lot of capsules this summer :).
Excellent job Mic&Mod !!

Exciting to build and a nice challenge to calibrate for highest output and lowest distortion.
Fantastic quality all the way through, don't think I'd be happier with an original... just poorer...

Very good cable!!!!

Very nice mic!!!! only one thing I couldn't find the microphone diagram…..Please…. Good work

SUPER

Nice little challenges.. probably not recommended as a 1st DIY Project...
Nice little suitcase for it, and so nice to look at... and touch.
The sound is also just delicious

Take your time when building, if you are careful and doublechecking everything all will be fine. What you get is a beautifully sounding microphone with low noice. I am more than pleased!

It was just a great experience to build it.
Top quality components.. and then that little black, cute tube
Top delicious sound and just lovely to look at and touch

Je viens de construire mon second M49. Testé et approuvé. J' ai maintenant un couple d'exception !

Just so amazing to look at, and touch... and amazing sound... top quality components, and a very detailed guide... makes the build a highly addictive experience

Got this microphone over a month now and i'm trilled! This comes realy close with the original, who a friend of mine uses in his studio. We compared the two and it's almost indentical to the Ela M 251 from Telefunken. And for this price... awesome!! It's now my "go to" mic for solo singers.

I bought 2 Kits as (quite cheap) overheads. They do not disappoint. The sound seems very neutral, almost as if it is a SDC.

I have only yet used it on Speech, Guitar (Electric and Acoustic) and Vocals.

Sometimes I miss the big sound of a LDC as I'm used to that, but these mics just work well in any condition, take EQ incredibly well, have more resolution and pressure than anything else under 1000€ that I've heard....I'm happy, despite not being used to the sound signature yet.

Thumbs up! Great Kit! The boy is a tad smaller than expected, lovely and more heavy than the cheapo 30€ mics.

I never dreamed that I could own a 251 in my life. I received the kit today which was very well packed and I started building immediately. I have some diy experience so it went pretty fast. The build was very comprehensive and easy to do with the instructions. This is a beautiful mic to look at! But the most important thing. The sound… I’m blown away by the quality. I’ve worked with many condensers and never heard anything like this. It’s a very very good sounding mic. I like it better than any u47’s I’ve heard but maybe that’s just my taste. This has more of a pleasing curve to start with. This is truly ‘capturing’ what I want it to.
It fits my vocals amazingly. It’s super low noise and just deep and 3d.
I might post an update once I’ve worked with it longer. But for now consider me impressed
