"...upgrade the inexpensive Oktava
012 mic from
modification replaces all the critical electronic parts with
quality parts, making a good microphone sound even better. It improves
and low end response, detail, and lowers the noise level. If your
are not in good working order
before the modification there may be an reasonable additional repair
charge. The repair fee will range from $15 to a max of $54,
depending on the complexity of the repair.
If you would
like to do
the modification yourself, all the parts are available in kit form with
012 mics benefit just as much as older ones.
On searching the Internet I find a significant amount of confusion on this topic. Many speculate that brand new 012’s have all the improvements already incorporated, so the modification will have no effect on performance. This is simply not true. Here are the facts, based on years of experience working with these microphones. New mics have two basic changes in addition to serial numbers. (1) New mics are slightly longer to accommodate a new style XLR base. (2) Oktava no longer uses any wet-slug capacitors in the 012. Old mics typically used wet-slug caps for C3, C4, and C5, and sometimes even C2. These wet-slug caps are prone to leakage and can even damage the circuit board. Most new mics use BBC caps, like the ones in the kit, for C3, C4, and C5. But beware; even brand new mics can use different brands of lower quality and various values. The majority of the sound improvement comes from the changes on the front of the board, where Oktava has made no improvements. In fact I see more variation of factory parts than on older mics. So YES, the sound improvement from modification is just as evident on new mics as older ones!
Russian made Oktava's. True Russian
012's came with the 10db pad and the metal mic clip and can
labeled MC or MK 012. Only newer ones (2002) have serial numbers. Click

Good soldering skills are required to perform the modification, especially the premium mod. The Circuit board is small and delicate and can be easily damaged. If you do not feel comfortable doing the modification yourself, you should send your mic(s) in for modification.

"Just got the mod today and installed it 5 minutes ago. First I made a mistake and put the tantalum cap wrong way, but then realized it and corrected it. Results: Wow!!! I made a "before" recording and "after" recording and the honky mid and not well defined bass is gone!!! I have recorded it through a nice Avedis preamp and it sounded beautiful!! Very balanced, especially the mid and bass is much more beautiful now!..Thanks ;)"

-NEW- I now offer the Premium Modification for the 012 in a kit. The premium mod provides a slight improvement in clarity over the standard mod for those who want the very best. The premium mod uses four 1G resistors in the front end. Please only consider doing this yourself if you have experience working with small electronics, the space is very tight.
