Microtech Gefell Expands Its Legacy with the UM 57 Reissue and New WP 21 Wind & Pop Filter
Celebrating Heritage While Embracing Modern Recording Needs
Few microphone manufacturers can claim a legacy as rich and influential as Microtech Gefell. With roots stretching back to some of the most revered microphone designs in recording history, the company continues to blend traditional craftsmanship with modern engineering. Two recent additions to the lineup perfectly demonstrate this philosophy: the return of the legendary UM 57 tube condenser microphone and the introduction of the WP 21 wind and pop filter for Generation 4 and M 300 small-diaphragm microphone systems.

The Return of a True Studio Legend
Originally introduced in the 1950s, the UM 57 quickly established itself as one of the most respected studio microphones of its era. Used in broadcast facilities and professional recording studios, it became renowned for its smooth frequency response, natural warmth, and detailed sound reproduction.

Now, Microtech Gefell has faithfully reissued this iconic microphone, preserving the original sonic character while manufacturing it to modern standards. At the heart of the UM 57 Reissue is the original M7 large-diaphragm capsule, featuring gold-plated PVC diaphragms that deliver the same rich and musical response that made the original famous. ⤵️

Authentic Tube Character for Today’s Studios
The UM 57 Reissue is powered by a carefully selected EF86 vacuum tube operating in triode mode, producing the harmonic richness and depth that engineers and artists continue to seek from classic tube microphones. Combined with the dedicated UN 57 external power supply, users can remotely switch between omnidirectional, cardioid, and figure-eight polar patterns, allowing the microphone to adapt to a wide variety of recording situations.
Whether capturing vocals, acoustic instruments, orchestral recordings, or room ambience, the UM 57 delivers a timeless analog sound that remains as relevant today as it was decades ago.
A Complete Premium Recording Solution
More than just a microphone, the UM 57 arrives as a complete professional recording system. The package includes the microphone, UN 57 power supply, tube connection cable, EA 92 elastic suspension shock mount, and a dedicated travel case. Every component reflects Microtech Gefell’s commitment to quality, precision, and long-term reliability.

For studios seeking a microphone with genuine heritage and unmistakable character, the UM 57 represents a rare opportunity to experience a true classic in modern production environments.
Introducing the WP 21 Wind & Pop Filter
Alongside the return of the UM 57, Microtech Gefell has expanded its accessory range with the new WP 21 wind and pop filter. Designed specifically for the company’s Generation 4 and M 300 small-diaphragm microphone systems, the WP 21 provides an effective solution for reducing wind noise and plosive interference without compromising the microphones’ natural sound quality. ⤵️
Designed for Demanding Recording Environments
The WP 21 incorporates a specialised acoustic design with additional internal flocking that improves airflow management around the microphone capsule. This construction helps minimise wind-related disturbances during outdoor recording while also reducing plosive sounds during close-miking applications.
As a result, the WP 21 is equally suited to field recording, broadcast production, location sound capture, studio voice recording, and close-mic speech applications.
Preserving Natural Sound While Improving Reliability
One of the biggest challenges with wind and pop protection is maintaining the microphone’s tonal integrity. The WP 21 has been engineered specifically to preserve the detailed and natural sound characteristics of compatible Generation 4 and M 300 microphones while improving recording consistency in challenging environments.

Compact, lightweight, and easy to integrate, it offers a practical upgrade for engineers and content creators who require dependable performance in both indoor and outdoor applications.
Tradition, Innovation, and Professional Performance
Together, the UM 57 Reissue and WP 21 demonstrate Microtech Gefell’s ongoing dedication to serving professional recording engineers, broadcasters, musicians, and content creators. One product celebrates the return of a legendary studio microphone, while the other provides a modern solution for cleaner and more reliable recordings.
Whether you’re seeking the unmistakable warmth of a classic tube condenser microphone or improved protection for small-diaphragm recording applications, these latest additions continue the tradition of excellence that has defined Microtech Gefell for generations.
