The Soul of a Legendary Tube Mic

This article was Written By

Get to know them!

Microphones — even the great ones — rarely reflect absolute sonic reality. Nor would we want them to. Sought-after vintage large-diaphragm tube condenser mics each flaunted unique characteristics that made them desirable for specific tasks. Frank Sinatra's vocal mic of choice, for instance, remains coveted for its authoritative presence and bottom end. The successor to that legendary mic, itself a classic used by everyone from the Beatles, Stones, and Bob Dylan to Nirvana, exhibited a gentler high-end boost and tamed proximity effect. This is the sonic essence of the Soundelux USA U99. Handcrafted by preeminent microphone designer David Bock, the U99 is a mic that does everything well.

Three polar patterns and tone-shaping control

With its three polar patterns (cardioid, omni, and figure-8), high-frequency boost-flat-cut switch, signature Soundelux fat circuit, and onboard pad, the U99 offers incredible versatility. Incorporating a new-old-stock tube and a true linear high-current power supply, the U99 boasts the flawless design and build quality typical of all Soundelux mics. It's a must-have studio mic, and it's rugged enough for onstage use.

The '99 delivers jaw-dropping realism

Due to its mild proximity effect, optimized signal-to-noise ratio, and moderately high gain, the U99 is ideal for both close and distance miking. Based around the storied K67 dual-membrane, dual-symmetrical-backplate capsule, the U99 delivers jaw-dropping realism on acoustic guitars and preserves the delicate timbral balance of acoustic pianos. Use it as close, overhead, or room mics to make a drum kit shimmer with energy and dimension. The '99 is perfect for strings and for voice-over duties. Lush without a hint of boominess, the Soundelux U99 serves up the sound of a perfectly maintained vintage tube mic, with state-of-the-art specs, performance, and versatility — and a warranty. It's a no-brainer: the U99 deserves a place of honor in your mic locker.

Handcrafted excellence delivers premium sound

When pro studios are looking to fortify their mic lockers with premium microphones, Sweetwater engineers often recommend Soundelux mics. These exceptional microphones are handcrafted with point-to-point wiring, time-proven transformer circuitry, and an attention to detail that truly brings the sound of prized vintage mics "back to life." David Bock, one of the world's leading experts on vintage microphones, doesn't compromise when it comes to components, construction, assembly, or testing. These mics are hand-tuned, using strictly tested European capsules and premium-grade electronics. The U99 comes with a proprietary N470 power supply, a 6-pin XLR cable, and a bottom-thread shockmount.
