The Mouse Large Diameter Cardioid Condenser

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.

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.
