Mojave Audio MA-37 Large Diaphragm Tube Condenser Microphone

The Mojave Audio MA-37 is a modern reimagining of the iconic Sony C-37A, meticulously crafted by David Royer to bring the vintage warmth and detail of this classic microphone to today’s studios. With an EF86 tube, Lundahl transformer, and a custom hand-built capsule, the MA-37 captures smooth, ribbon-like sound with remarkable headroom, ideal for taming brittle high frequencies on vocals, guitars, and more.

A dedicated power supply offers high-pass filter options at flat (M), 100 Hz (V1), and 200 Hz (V2) to accommodate different recording environments.
