David Royer of Technical Grammy Award recipients Royer Labs has always counted the Sony C-37a among his favorite microphone designs. With the Mojave Audio MA-37 large-diaphragm tube condenser microphone, David has brought a long-time dream to life: an updated version of an undeniable studio classic. The C-37a is considered something of a “secret weapon” among artists and engineers, given its smooth ribbon-like sound and high headroom. The MA-37 nails the sonic characteristics of its inspiration and retains its signature u-shaped yoke, adjustable tuned acoustic chamber for switching between cardioid and omnidirectional operation, and compact form factor. After employing the mic in numerous applications, engineers at Sweetwater found that MA-37 has an uncanny ability to flatter any source — vocals are rich, detailed, and dripping in vintage-tube-mic vibe; acoustic instruments bloom with a natural, open presence; and guitar amps benefit from a smooth yet upfront mid-range that helps them drop right into a mix. Simple and elegant, the MA-37 is a worthy successor to a mic-locker legend!
