All of MXL's transformerless microphones are wonderful candidates for an upgrade. We've developed a mod kit that turns these mics into high sensitivity, low noise, multipattern microphones. Just follow these two easy steps.


Step 1 is to replace the stock circuit with our "MP-V57" PCB kit. The kit includes a high-quality two-layer PCB (made in the USA), and handpicked audiophile-grade components. You just need to solder it all together.

RK-47 Capsule

Step 2 is to pick from any of our six large-diaphragm capsules. We have so many choices because they all sound different. This is the best way to build some sonic variety into your mic locker!
