C12 DIY Kit

The outsider


Our kit is a perfect clone of the legendary AKG C12 tube microphone, the standard for years in the recording industry and studios around the world.

The original sound

With the CK12 capsule according to the original specifications, the sound of our kit is faithful to the original microphone found in the world’s largest studios.

The perfect clone

The schematic is a full replica of the original microphone. It is a side-address, large-diaphragm design based on CK12 capsule, a 6072 dual-triode glass tube, and a T14 transformer-coupled output circuit. All components are carefully matched and selected in our workshops. We attach great importance to the precision of our circuits to be as accurate as possible compared to the original.

" Full, open sound on drums in my little room and lovely high frequencies, so much better as overheads instead AKG C414 or Neumann KM184. "

" I Love everything about this mic. I went with the General Electric 12AT7wc Tube and the NOS Russian Oiled Paper Output capacitor. Ordered a pair and these are my new favourite mics in my locker. So smooth!!! Great lows without being woofy, a soft transient response without ANY loss in clarity and presence. I can't imagine a situation that this mic wont shine in. Thanks So Much!!! "

" Magnifique micro et facile a monter 😉 La limited edition est superbe avec une couleur brillante et bien terminé. Le montage n'a pas été trop fastidieux si on connait bien son fer à souder (les cours de techno auront servi à qq chose !). Le temps de montage est grossomodo de 5h avec calibrage. J'attends avec impatience le nouveau kit U47 ! "
