Featuring a hand-tuned capsule and quiet Class-A discrete circuitry, the Blue Baby Bottle SL is a studio condenser microphone which builds upon its predecessor to provide a warm and classic sound as well as switchable filter and pad settings, ensuring great versatility for varied studio recording applications. It utilizes a large, gold-sputtered Mylar diaphragm, replete with a machined brass backplate to yield its signature sound—supple highs, rich midrange, and honest bass. Further elevating its professional nature is the custom shockmount, which absorbs vibrations to inhibit handling and stand noise.

Classic Warmth and Presense

Baby Bottle SL is a cardioid condenser microphone that delivers classic sound and incredible versatility. With a richly present midrange, smooth top end, and neutral bottom, Baby Bottle SL is reminiscent of the world's finest vintage microphones. Featuring a high-pass filter and -20 dB pad, Baby Bottle SL excels at adding a rich, classic vibe to nearly any sound source.

Behind the Mic

Building on the success of the original Baby Bottle, the SL model features refined sonics, a new streamlined build, and versatile switches to capture the true character of your voice and bring classic mojo to acoustic guitars and other instruments. Baby Bottle SL is designed from top to bottom to inspire unforgettable performances.

Inside the Sound

The soul and swagger of Baby Bottle SL all starts with Blue's proprietary, hand-tuned capsule. The robust, gold-sputtered Mylar diaphragm features a machined brass backplate design that creates the signature warmth and presence Baby Bottle SL is known for. And custom Class-A discrete circuitry makes it an extremely quiet mic with only 10.8 dB of self-noise.

Make the Switch

Baby Bottle SL features a switchable 100 Hz high-pass filter and -20 dB pad to keep your sound pure regardless of vocal type, instrument, or environment. Whether recording belting vocalists, loud guitar amps, drums, and brass, or capturing delicate vocals, strings, or piano, Baby Bottle SL has the versatility to capture timeless tracks.
