Meet the Bottle Rocket Stage One. The Stage One is our most accessible Class A discrete solid state mic with a foundation for interchangeable capsules including Blues nine vintage lollipop-style capsules the Bottle Caps. This bayonet-mounted system gives the user unlimited flexibility and a wide variety of tonal characteristics and pickup patterns all in one mic!
Precision-designed and hand-assembled the Stage One is crafted for a lifetime of use. Compared to similar microphones the Stage One had a very low self noise specification (< 7.5 dB) and an very high output level (+12dBV) making it the perfect choice for todays high sample rate/deep word length digital platforms. Instead of integrated circuits (chips) the Stage One employs a transformless Class A discrete amplifier circuit to ensure the most accurate and noise-free signal possible with minimal distortion and coloration. The Stage One is an ideal microphone for recording virtually any sound source. In addition to the microphone the Stage One also includes Blues custom spider shockmount.
