The Warm Audio WA-251 Tube Condenser Mic was created to offer a classic microphone design to a mint generation of recording artists at an affordable price. Warm spent a great deal of time listening to different ‘251 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.
