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. Like the Bottle, the Stage Two has the ability to hot-swap up to nine different capsules for the ultimate recording experience. The Bottle Rocket Stage 2 is powered by Blue’s innovative Powerstream power supply, which not only ensures ultra-stable performance but features a soft-start feature for maximum tube life and minimal startup time.
