The 990 has the full upgrade treatment including:

  • k47 Style Large Diaphragm Capsule
  • jsSb Circuit Board with optional internal pattern switch
  • Matte Red paint finish

The 991 is stock and unmodified. It can drastically improved by swapping the capsule with a SDC capsule from mic-parts.


  • Mic-Parts improved headbasket for the 990 (looks better, sounds better)


  • Internal pattern switch is accessed by unscrewing the body cylinder.  In omni mode the signal level of the mic decreases about 6dB.
  • The Mic Parts Headbasket does not have a Cardioid Emblem on the front as seen in some photos

Contact me if you have any questions about the mic.
