Studio Tube Microphone with Interchangable Capsules

Manufacturer Description:

Designed for speed and transparency, the Stage Two vacuum tube microphone’s transformerless, Class A discrete tube amplifier circuit delivers low noise, superb transient response and utilizes a single hand-selected ECC88 vacuum tube.
