Choosing the Right Mic for your Sessions

Recording with Vintage versus Modern Mics


Bottle isn’t just a microphone—it’s a complete microphone system that features nine interchangeable mic capsules. Each of these nine Bottle Caps delivers a distinct pickup pattern and tonal characteristic to suit any instrument, vocalist, ensemble, or recording style. Bottle’s simple bayonet-mount lets you swap between capsules effortlessly—without turning off the power supply—so you can experiment with new sounds or layer tracks for lush sonic textures, instantly. No warm-up. No downtime. Just pure, uninterrupted performance so you can stay in the creative flow of your session.

Meet the Bottle Caps


With its impressive size and nostalgic resemblance to the earliest European tube microphones, Bottle radiates a gravitas that inspires once-in-a-lifetime performances. Like the mics of yesteryear, the Bottle body isn’t just for looks, but also holds a small fortune in precision electronics.

Bottle’s internal circuitry is thoroughly modern, with a fully discrete Class A tube circuit powered by a hand-selected EF86 pentode vacuum tube in triode mode for distinctive warmth and saturation. The hand-wound transformer—made of silver wire around nickel plates—delivers precision and accuracy due to the high conductivity that silver offers. Bottle utilizes electronic components of tthe highest quality (such as expensive metal-film resistors), with absolutely zero pad or low-cut filter switches in the microphone circuit. In short, this is a signal path of the highest possible quality, allowing you to get the maximum benefit out of the unprecedented capsule selection we’ve created.


Every Bottle microphone comes with our signature B6 large-diaphragm dual-backplate cardioid capsule. B6 holds the honored title of the “Blue Standard” and delivers larger than life sound with enhanced lows and extended high frequency response. It’s the ideal capsule for recording lead and background vocals, percussion, and guitars—all with detailed sonic dimension and character. And when you want to modify the tone and sonic signature of your Bottle, just swap the B6 for one of the interchangeable Bottle Caps to achieve any sound imaginable.


The Power Stream is more than a precision-engineered power supply that delivers clean, extremely consistent power to the Bottle. It’s also an innovative and creative tool for fine-tuning the Bottle’s sound. Both the heater and the plate voltages are ultra-stable and non-dependent on AC changes of fluctuations. For AC rectification, the Power Stream uses only high-frequency diodes to obtain the purest DC possible. And most importantly, the plate voltage supply is of low impedance, which improves sonics and clarity. All the potentiometer switches on the Power Stream are discrete military grade with enclosed contacts.



The Power Stream offers a nine-step sensitivity knob that allows you to determine precisely the right polarization voltage to achieve your desired sound. Rotate the switch counter-clockwise to tame an edgy sound source. Or rotate clockwise to increase the sensitivity and drive the capsule harder to add vibrancy and richness to quieter performers.

Each of the Bottle Caps respond differently to the various sensitivity settings, so when combined, the Bottle takes on a nearly infinite sonic palette. With a range of minus 6dB to plus 4dB of sensitivity, the 9 positions offer an opportunity to dial in the sweet spot and customize the sound of the Bottle to perfectly capture the unique sonics and character of your vocalist or instrument.


The Bottle’s release announced a new standard for pro-audio design innovation and performance—the Blue standard. Now the world’s most elite studios and top artists rely on Blue microphones to craft and memorialize their iconic sounds. Bottle is designed and hand-built in the USA, and delivers our heritage for superior studio-grade audio and inspiring design. Define your sound with the mic that changed everything—The Bottle.
