The Bottle Cap Series offers an unprecedented creative palette for Bottle and BottleRocket Stage One mics. Inspired by the most coveted mics in recording history and forged for modern applications, the Bottle Caps embrace the past to define the future. The series delivers an extraordinary variety of timbres and polar patterns—with options ranging from vintage to modern—forming a world-class collection that would cost tens of thousands of dollars to obtain with individual mics. With the Bottle Caps, you can capture the unique character, dimension, and nuances of timeless performances from any vocalist or instrument.
Superior bright, silky, and intimate presence.
Ideally suited for lead and background vocals, guitar, mandolin, percussion—any source where extended top end is featured.
Inspired by the vintage tube microphones that became pro audio milestones, B0 delivers an updated version of the warm, smoky vocal sound that defined a generation of legendary singers.
Sonic accuracy with extended high-frequency response
Perfect for nylon or steel-string acoustic guitar, accordion, drum overheads, metal percussion, hi-hat, small pitched percussion such as toy piano or marimba, room or ambient miking, foley and sound effect recording, strings and orchestral recording.
B1 was fashioned after ultra-responsive classic tube mics that flattered high-frequency and extended-frequency instruments. By adding in proprietary Blue design elements, B1 produces crystalline accuracy and precision highs while maintaining a smooth signal for tracking instruments with fast transients and rich overtones.
Big, warm, and full sound reminiscent of vintage ribbon mics
For bringing out the warmth of vintage brass and woodwinds, jazz and horn ensembles, all extended-range strings and bowed instruments, acoustic and electric guitars, slide guitar, vocals and organ.
B2 pays homage to the full sound of classic ribbon mics in a whole new way. Outfitted with a condenser capsule, B2 is able to replicate the sound of vintage ribbon mics while bearing up to higher SPL for an exquisitely present timbre.
Ultimate transparent, neutral sound
Perfectly suited for female vocals, distant miking orchestral groups and instruments, banjo, mandolin, resonator guitar, jazz guitar, distorted electric guitar, electric bass, a natural or “folky” acoustic guitar tone, double reeds and organ.
With B3, we set out to deliver the sonic precision of classic cardioid settings. B3 brings a proprietary dual backplate capsule design that yields accurate recording tones when used with vocals and instruments—and it smooths out the top end with an added 2dB at 12kHz.
Sweet highs and robust lows with a unique design and sound perfect for ambient recording.
Captures the atmosphere of orchestral sounds, classical instrumentation, background vocals, organ, accordion, distant miking of any source, particularly bowed strings, and drums.
Based on the most sought-after omni tube mics, B4 delivers a very smooth sonic character with a slight boost in the bottom end around 80Hz. But unlike its predecessors that were inaccurate when miked in stereo, each B4 is sonically matched together.
Unique compressed quality with accentuated low- and high-frequency response
Perfect for instruments that need close miking or presence boosting to cut through the mix, such as acoustic guitar, percussion, piano, or other acoustic sources.
B5 produces the massive sound of widely celebrated Eastern Block pressure omni tube mics. It features a contoured sound with an 8-9dB depression at 400hz.
“Larger than life” sound with enhanced lows and high frequency presence
Yields robust lead and background vocals, voiceovers, percussion, piano, vibraphone, accordion, clean electric guitar, jazz guitar, and distant miking of acoustic or resonator guitar.
Influenced by elite vintage tube mics, B6 was developed to deliver powerfully rich tones without any of the drawbacks of its predecessors. B6 eschews high- and low-pass filters to yield an even smoother, more robust tone. It’s further enhanced by custom ceramic tensioning rings that eliminate the dreaded dropout of those earlier designs. The capsule also features a gold sputtered film for increased punch in the higher and lower frequencies—giving the B6 its very modern sound.
Classic vintage detailed mids with airy presence
Complements the details of classic lead and background vocals, saxophone, flugelhorn, clean or distorted electric guitar, pedal steel and slide guitar, organ, conventional jazz recording.
The B7 capsule was born from our history of repairing and modding the classic mics owned by artists like Paul McCartney and John Lennon. B7 provides a tone reminiscent of the greatest recording mics of the 1940’s and 50’s, while adding in enhanced highs for a slight contemporary kick. It’s the ultimate in vintage detail and modern presence.
Crystal clear sound quality and excellent detail for a wide range of recording applications. If you choose only one capsule, B8 is known for being the most flexible.
For tracking a variety of male and female lead vocals, electric & acoustic guitars, drums, drum overheads, percussion, piano, horns and strings.
B8 is a hot-rod version of one of the world’s most famous condenser capsules. But unlike the capsules that inspired it, which were lacking in mids, B8 offers added midrange for fuller tone and a proprietary backplate design that makes it perfect for recording just about anything.
Commanding performances that sit in front of the mix
Perfect for recording vocals and acoustic guitar that sit in front of the mix
A new sound all its own, the B9 features a shimmering high-end, smooth midrange and intimate presence that delivers commanding vocal and acoustic guitar performances that sit in front of the mix.
Smooth, yet full sound with silky highs and a defined low end.
Perfect for female vocals, saxophone, violin and other higher frequency instruments.
Extending the Bottle Cap series, the B10 features smooth, yet full sound with silky highs and a defined low end that is great for difficult to tame sound sources.
Round, classic sound with a rich, vintage mid-range.
Perfect for capturing vocals and instruments with vibe and character.
