MOJAVE MA-37

LEGACY TUBE SOUND. REBORN FOR TODAY’S SESSIONS.

When he set his sights on reinventing the Sony C‑37a, TECHNICAL GRAMMY® Award-winner David Royer didn’t just pay homage. He crafted a modern thoroughbred that performs without having to baby it like a museum piece. The NAMM TEC Award-winning MA‑37 delivers that headroom-rich tone beloved in the golden age of Hollywood recording combined with rock-solid reliability that today’s sessions demand.

“The sound of the MA‑37 is quite special and unique…Most modern large-diaphragm mics lean bright. This one leans the opposite way, with a dark and smooth timbre…Guitar amps sound amazing…even roaring stacks won’t overpower it.” – Tape Op

Mojave Audio’s MA‑37: The connoisseur’s mic built for pros who know what they want.
