Warm Audio WA-251 Tube Condenser Microphone

The WA-251 was created to offer a classic microphone design to a new generation of recording artists at an affordable price. We spent a great deal of time listening to different microphones to determine what people liked about them and why, how various styles of components impact the tone, and how to give the WA-251 microphone a signature that pays homage to the vintage classic, but also stands out on its own.

The WA-251 is an all vacuum tube, large diaphragm, transformer balanced, multi-pattern, large condenser microphone, based on the classic, that has been used on countless hit records for the last 50+ years. The WA-251 is designed for pro studio, home studio, live, and broadcast applications and sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments, and an array of other sources.
