Description
Introducing the Blue Baby Bottle SL - a versatile, pressure gradient cardioid condenser microphone designed for both professional and amateur musicians. This microphone combines classic sound quality with modern technology, offering a rich midrange, smooth top-end, and neutral low-ends.
Its unique tonal characteristics are akin to the world's finest vintage microphones, but what sets the Baby Bottle SL apart is its ability to excel in recording from a vast array of sound sources. Whether you're capturing vocals, laying down a drum track, recording electric guitar amps, or even challenging brass instruments like saxophones and trumpets, the Baby Bottle SL is up to the task.
With a high-pass filter and -20dB pad, the microphone is perfectly equipped to handle loud sources without compromising on the quality of quieter, more nuanced performances. The inclusion of a -20dB pad switch allows you to gain-stage like a pro, providing ample headroom for recording loud sources and capturing more detailed sounds from quieter instruments.
The Baby Bottle SL's high-pass filter switch also helps eliminate low-end rumble, often caused by recording frequencies under 100Hz. With this roll-off switch engaged, the Baby Bottle SL is an excellent choice for recording acoustic instruments and can even be used as a stereo pair to record complex instruments or create a natural reverb for a variety of sounds.

Thickens whispy vocals, loves bass-heavy sources. Takes a lickin'!
The baby bottle is a solid state, side-address large diaphragm condenser. Cardioid pattern only. Though it has the german bottle thing going, the capsules is not removeable/changeable. This mic adds girth to every sound you put it in front of. I don't know if it has an output transformer, but maybe it does. I really like this microphone on whispery and croony singers. Its also a great about 2 feet from a bass amplifier. Hypes the low end just right while getting all the stringiness. Not great for much else. Not bad, but not great.
I traded mine to a pal for a marshall 1960 cab when I needed a spare. No regrets.

I simply love this mic; it pics up everything! It has a pretty neutral tone. Consequently, I've used it for recording both men and women. It's extremely versatile and cost effective!

great mic, owned one for years, though I found it to be best suited to female vocals and instruments, but YMMV... why are you speaking in the third person in all of your reviews?

and a good one it is too, strangely underrated too... the original foudners of BLUE have a new company now, forget what its called, but they have a new lollipop hitting shelves now that got a very favorable review in the last TapeOp
