Description
This is a Mod / Rebuild of your microphone.
The standard MXL mass-produced circuit board is replaced with our BFM Transformer-Coupled Circuit and high quality Transformer. We replace the small stock MXL capsule with a quality LDC. Circuit and Capsule are carefully connected with point-to-point wiring. These are not kits from mic-parts or others.
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 stock MXL headbasket can be left alone, Improved or Replaced. We can improve it by removing some of the inner mesh layers. We can swap it out with a high quality replacement from mic-parts.com (subject to availability).
Standard Upgrade:
- Replace MXL SDC capsule with a K47-style or CK12-style LDC
- Replace MXL Electronics with our fully discrete BFM Transformer-Coupled Circuit.
Options:
- Choice of 3UAudio, CineMag or AMI Transformer
- Internal Cardioid/Omni Pattern Switch.
- Improve the existing Headbasket by removing screen layers.
- Replace existing Headbasket with one from Mic-Parts
Contact me first if you have any questions about the upgrade or the options.
There is a modest drop in output level when putting the mic in omni mode with the internal pattern switch

AKG C414, Rockscience 990: they sound so similar.
990 before vs after? Night and day difference. I recorded a before and after comparison and the the response was much more even and flat compared to before with a much better low frequency response. This mic was recording down past 20hz at flat response levels. It responds how one would want a high end mic to respond.
Sounds great, feels great, looks great, absolute STEAL of a microphone for the price point. I’d do it again in a heart beat

I really was just trying to make my mic usable. I was not expecting it to be the go-to that it has become. Thank you so much! I knew there was some reason that I plunked down good money on those “Labor Day Specials” so many years ago.

I went with the AMI Tab-Funkenwerk T12 transformer and the CK12-Style Edge-Terminated capsule in my 990 and what a huge difference it made! I did some before and after recordings and really liked the results. I can confidently say this is the best mic that I own and would highly recommend.
