Studio microphone Warm Audio WA-67

The Warm Audio WA-67 is a large-diaphragm tube condenser microphone inspired by the classic ’67 studio microphone. Built around an EF86 pentode tube and a brass capsule assembly, the WA-67 is designed to deliver the smooth, creamy tone associated with the original vintage design while remaining affordable for modern studios. It is suitable for recording vocals, acoustic and electric guitars, drum toms and overheads, pianos, brass and strings.

Advantages

The WA-67 reproduces the characteristic sound of the original ’67 through a carefully recreated brass capsule and a discrete tube circuit. High-quality components such as polystyrene and boutique polypropylene capacitors, a large output capacitor, and a Lundahl custom transformer contribute to a wide bandwidth, smooth high-frequency response and three-dimensional sound. The microphone is housed in nickel-plated brass for durability and shielding, and it ships with a high-end GAC-7 7-pin cable to ensure reliable audio and tube power connections.

How to use

Connect the WA-67 to its dedicated power supply using the supplied Gotham GAC-7 7-pin cable, ensuring correct pin alignment. Allow the tube to warm up for a few minutes before recording to reach stable operating characteristics. Position the microphone according to the source: for close vocal work place the capsule 6–12 inches from the singer with a pop filter if needed; for guitar or piano experiment with distance and off-axis positioning to find the desired tonal balance; for drums use the WA-67 on toms or as overheads to capture a rich, full sound. Use a quality preamplifier with adequate headroom to accommodate the tube output and maintain low noise.

Recommendations

The WA-67 performs best when paired with a clean, high-headroom tube or solid-state preamp and the included GAC-7 cable. Allow warm-up time for consistent tone and protect the capsule during transport. For vintage-style recordings, try slightly off-axis placements and moderate room ambience to take advantage of the microphone’s three-dimensional character.
