Blue Microphones

The Blue B1 Bottle Cap was was designed to make your Blue Bottle perform like a vintage tube mic! It is perfect for capturing nylon- or steel-string guitars, small-pitched percussion, and orchestral string response. It's also great for drum overheads, ambient/room miking, and even Foley and sound-effect recording.

The Bottle Caps are Blue's innovative system of nine interchangeable capsules, each offering the recordist a different tonal characteristic and pickup pattern. From airy highs to larger-than-life lows, the Bottle Caps capture anything from vocals to bass, wind instruments to horns — and everything in between with a level of detail and clarity found in only the most expensive and rare vintage classics. The Bottle Caps work with Blue's Bottle, Bottle Rocket Stage Two, and Bottle Rocket Stage One mics, or any microphone with a foundation for interchangable capsules. Each capsule in the series is numbered from B0 to B8, and each has their own unique sound.
