MXL 990 Mods

MXL 990 Microphone

We have three modification options for the MXL 990. Are you looking for a simple upgrade, or a full rebuild? We have what you need.

We even have a video about it:

#1: Capsule Replacement

RK-47 capsule

If you've never upgraded a mic before, you might wish to start with something very simple. The mic's capsule gives you 90% of the sound of the microphone. In the case of most inexpensive condensers, the capsule is a $5-$10 part that, frankly, does not sound very good. Our line of premium replacement capsules will re-voice your mic, giving you a much smoother and more musically useful sound. In the case of the 990, a new large-diaphragm capsule will lower the mic's self-noise too. And it can be replaced by soldering just two wires. For the MXL 990, we recommend the RK-47 or RK7. Both make wonderful all-purpose microphones, with great detail in the mids, and a neutral to dark top end -- a welcome contrast to most over-bright condensers.

#2: 990B Circuit Replacement Kit
