Manufacturer's Description from Blue

The Blue Bottle is a classic modern vacuum tube microphone made the old-fashioned way, without compromise. In every industry — cameras, automobiles, audio, and more — there are a handful of small companies reputed for a rare blend of scientific precision and artistic passion. You know who these artisans are; their trademarks are synonymous with the ultimate in handcrafted perfection.

Our flagship “The Bottle” microphone parallels this vision, representing Blue’s highest achievement in quality and innovation. The Bottle is a precision recording tool, combining the low noise and superb transient response of top-grade electronics with the sonic magic of legendary vintage vocal microphones.

The Bottle is not simply a microphone, but a fully featured microphone system with eight optional interchangeable capsules. In an instant, these bayonet-mount capsules can be exchanged to provide different tonal characteristics and pickup patterns— while the power supply is still turned on!
The basic Bottle system includes a B6 cardioid capsule, Champagne tube microphone cable, an the Power Stream Tube Mic power supply, shipped in a blue velvet-lined ATA flight case approved for the utmost protection. The Bottle is finished in a luxurious blue lacquer paint.

The Bottle is unquestionably an impressive sight, with its imposing size and nostalgic resemblance to the earliest European tube microphones. Like the mics of yesteryear, the Bottle canister is not just for looks, but also holds a small fortune in precision electronics.

The internal circuitry of the Bottle is thoroughly modern, of course, with an amplifier design utilizing a single hand-selected vacuum tube pentode EF86 in triode mode. The tube circuit is Class A and fully discrete, meaning that the sound which arrives at the diaphragm of the Blue capsule is transduced (converted to electrical energy) as accurately as possible, with no integrated circuits (a.k.a “IC’s”) in the signal path. To this end, the Bottle utilizes electronic components of the highest quality (such as expensive metal-film resistors and large custom-built transformer), and there are no pad or low-cut filter switches in the microphone circuit. In short, this is a signal path of the highest possible quality, allowing the user to get the maximum benefit out of the unprecedented capsule selection created by Blue.

In order to get the most out of this, or any quality microphone, it is essential to pair it with a good microphone pre-amplifier. Most professional recordists prefer to have outboard preamps on hand, and will choose solid-state or vacuum tube models based on their unique characteristics. And unlike many tube microphones, the Bottle can be run through a variety of tube preamps without excess coloration, noise, loss of detail or tube compression.

The Bottle is Blue's flagship recording tool and its highest achievement in quality and innovation. It combines low noise and superb transient response integrated with a system of interchangeable capsules, the Bottle Caps. In an instant, the bayonet-mounted Bottle Caps can be exchanged to provide different tonal characteristics and pickup patterns while the included power supply remains on. The Class A discrete amplifier circuit of the Bottle is a thoroughly modern homage to the past, with a design utilizing a single hand-selected EF86 pentode vacuum tube in triode mode. The Bottle is the definition of craftsmanship, with hand-assembled custom components found throughout. With eight different Bottle Caps to choose from, the Bottle provides the ultimate recording experience for any application.
