Finished Rebuilt MXL 990 With 991 SDC

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.

Options:

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

Notes:

• 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
