With Hemisphere Mic Modeling

A modern classic for snare, percussion, and guitar amps.

Easily capture snare and tom drums, loud guitar cabs, brass, and more with SD-3 — a classic dynamic mic with high SPL handling, cardioid polar pattern, and best-in-class Hemisphere mic modeling giving you pro sound in any environment.

Record Through Five Workhorse Mics

SD-3 is powered by the same mic modeling technology found in our award-winning UA Sphere microphones. With the included Hemisphere Mic Collection software, it’s the only dynamic modeling mic that gives you the authentic sound of famous dynamics from Shure, Sennheiser, and Audix.* See included mic models ›

      A Modeling Mic That Works for You

      SD-3 and the included Hemisphere Mic Collection software work with or without UA hardware, and go way beyond subtle EQ curves to give you precise control over filter, proximity, and axis — an industry first. Just set up SD-3 and use the plug-in to find that “sweet spot” for a guitar cab, or tame harsh frequencies on a snare or tom drum.

      Easily Capture Your Best Sounds

      We fine-tuned the cardioid polar pattern on SD-3 for a wide range of environments. Whether it's your bedroom, project, or pro studio — or even the stage — SD-3’s ultra-high SPL tolerance and exceptional isolation give you iconic "sit-in-the-mix" sounds heard on countless hits. Plus, its compact size lets you zone in for perfect mic placement in tight spaces.

      Add a Pro Mic with Vintage Style

      With all-metal construction, retro fit and finish, and hand-selected capsules, the SD-3 stands apart from other "workhorse dynamics" — giving you a trusted partner, perfect for capturing nearly any source.

      Make it a Three Pack

      SD-3 is also available in a three pack, ideal for miking up a full rack of tom drums, or your entire backline.

      Included Hemisphere Mic Models



      The DN-4 is based on a modern compact instrument mic that works great on toms, but is equally at home on guitar cabinets and snare drums. We included a three-position filter to allow you to further sculpt the sound.



      Introduced in 1965, the ubiquitous “57” is very likely the best selling microphone of all time. It can be a particularly good option when blended with other mics, such as ribbons and large diaphragm condensers, to achieve a more balanced sound. Our DN-57 is based on a recent production model.



      The 409 shines on many sources, but is particularly well-suited to electric guitar amps. It has a smooth top, and its low-end response below 100 Hz can help instruments and vocals sit nicely in the mix.



      A predecessor to the mighty 57, this model employed the Unidyne III capsule. It was used extensively on The Beach Boys Pet Sounds, including Brian Wilson's lead vocal, and countless other recordings of that era.**



      The DN-604 model is based on a current production European-made 604, which has become a standard on stages and studios around the world. This compact clip-on mic has a variety of uses, most notably snare and tom drums.
