This is a rebuild of YOUR transformerless microphone which will convert it to a transformer coupled mic.

Since this covers a variety of different mics, please contact me before purchasing. 

Your low-end, low-cost mic is transformed into a very solid performer – with a little extra Transformer Mojo.  Harsh, sibilant high-end becomes smooth and silky. Thin bottom end becomes full. In the middle is a great harmonic richness that works well on almost anything you throw at it. The transformer brings some fantastic dynamics and saturation characteristics.

Your modified microphone will be returned after just a few days in our shop.

Standard Upgrade

  • k47 style Brass Ring or CK12-style* Capsule in Custom Mounting Cradle
  • All-discrete BFM transformer coupled circuit (Cardioid only)
  • Transformer mounting board

Options Available:

  • Internal Cardioid/Omni Pattern Switch (you must open the mic to access it)

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 capsule may not fit in all mics.

    I had two Sterling mics upgraded and they are a huge upgrade from the original product. I highly recommend anyone getting an upgrade from Rockscience.
