What We Think

If you've read the product description or any other marketing materials about this mic, you already know that blue is proud of this mic on low frequency sources - kick drum, bass guitar, cello, baritone voice, etc...They've made a big deal about it, and they're right to be proud. It's a tight sounding, crisp but huge sounding low end to the mic. It works well on sources where you really want to emphasize the low end, but it's important to note and often overlooked that this mic isn't so focused on low end that it's bad on other sources. A quick look at its frequency response (you can find it in the photos area above), and you'll realize that it's actually quite flat through the low end with a presence peak around 5.5k. There's clearly a lot going on with this mic that doesn't show on the frequency chart. It's not overemphasizing the low end, but boy does it really make the low end sound good.

Don't hesitate to get this as your primary general purpose mic though - it's quite responsive to EQ, so you can push it in whatever direction it needs to go. It's still a great option for female vocals, wind instruments, and guitar tracks.

Manufacturer's Description from Blue

The Blue Mouse is a classic modern microphone made the old-fashioned way, without compromise. The unique rotating capsule (also utilized on the Blue Dragonfly) makes this one of the most versatile and snazzy-looking mics you’ll ever lay eyes on. And beneath the handsome exterior, you’ll find that the Mouse is a precision recording tool, combining the low noise and superb transient response of top-grade modern electronics with the crisp, airy high end magic of legendary vintage vocal mics. In order to familiarize yourself with this microphone’s specialized and unique features, please take the time to read this manual, and be sure to try the suggested recording tips.

The Mouse is a pressure-gradient cardioid condenser microphone, employing the Blue single-membrane, factory-tuned large diaphragm capsule. For this hand-crafted diaphragm we have selected a 6-micron mylar film, sputtered with a mixture of pure gold and aluminum, and tensioned to our own hand-built brass backplates. Enclosed within a rotating spherical grille, the capsule can be positioned and adjusted in the smallest of spaces. This innovative design offers fine-tuning and precise placement to please the most discerning recordist, combined with an ease of use that is without equal among either vintage or contemporary microphones.

First and foremost, the Mouse has been designed to provide the commanding, intimate presence associated with the world’s best (and most expensive) vintage vocal microphones. With its shimmering, detailed highs, smooth mid-range, and minimized proximity effect (a bass boost inherent in all unidirectional mics), this capsule design excels at delivering a vocal right to the front of the mix where it belongs. When processed with limiting and/or compression, as is standard practice for most pop vocals, tracks recorded with the Mouse will be free of pumping and low end thumps. Acoustic guitar, hand percussion, drums, and other critical high end sources also shine in front of the Mouse, gaining an extra measure of “air” and presence that enables the most delicate sounds to cut through a mix, even at very low levels.

The Mouse's hand-tuned capsule is specifically designed to capture the thundering lows of bass and baritone vocals and low-end instrument sources. Enclosed within a rotating spherical grille, the capsule can also be positioned and adjusted into the smallest of spaces for applications where versatility is paramount. The Mouse is perfectly suited for kick drums, acoustic bass, electric bass amplifiers, snare drums, broadcast and voiceover work, and any other sources where accurate reproduction of low frequency transients is paramount.
