This mic mod/rebuild applies to transformer-coupled mics such as the MXL2001 or M-Audio Nova (and many others). Your mic’s capsule, electronics and transformer are fully replaced drastically improving the tone and performance! This is a mic mod well worth doing. An optional internal pattern switch allows switching between Cardioid and Omni. Without the switch, the mic is fixed cardioid.

This is a rebuild of YOUR transformer-coupled micPlease contact me before purchasing. 

Standard Upgrade

  • k47 style Brass Ring or Ck12-style* Capsule in Custom Mounting Cradle
  • All-discrete BFM transformer coupled circuit (Cardioid only)

Transformer Choices

  • CineMag (USA) 5722w. This is a very high quality transformer which is still moderately priced. It has a very full, even tone with great harmonic content and transformer crunch. Probably the best choice overall for most applications
  • The Tab-Funkenwerk (USA) T12 style. This is a more expensive transformer. It has a massively fat and full low and low-mid response. Although it has great high frequency response, you may perceive the overall tone as slightly dark because of the extra full lows and low-mids.

*CK12 style capsule may not fit in all mics.

    Yes, I could have just purchased a higher quality mic. I already have several in my locker now, my goal was to take one of my first inexpensive mics that I had ever purchased and see what the outcome may be. If you’re at all considering doing the same, do it! Hey it’s no $10k mic now but the performance far exceeds my $600-$1k mics that I currently own. I have been using it for recording a female vocalist currently with amazing results. Very satisfied with the mod, and I highly recommend the upgrade. Thanks Rockscience.
