Upgrade your MXL 990 mic with a Ribbon Microphone Modification

Add the weatherstripping to the sides of the Ribbon Motor as shown in the original DIY Ribbon Mic Plans, then install the motor into the MXL 990.

To fit in the chassis, the Ribbon Motor must be shorter than 2.54" - that is just barely taller than the completed ribbon motor asssembly.  If you need to trim the ends, do so.  Don't force the motor into the chassis, or you're likely to have a short circuit.

Put everything back together again, less the original condenser element and circuit board, and you have a ribbon motor in your MXL-990 Chassis.
