Sound Pure's Take

The Soyuz 013 FET (available as single units or hand-matched stereo pairs) is a small-diaphragm condenser microphone that redefines the standard for pencil condensers by pairing pristine transient speed with a rich, musical body. Handcrafted in Tula, Russia, the 013 FET features a custom-designed sub-miniature cardioid capsule paired with a proprietary transformer-balanced output circuit, delivering a detailed top end without the sharp, overly bright high-frequency tilt common to modern pencil mics.

Unlike typical SDC microphones that tend to sound thin or overly clinical, the 013 FET retains an exceptionally smooth, natural top end while capturing deep low-end body and authoritative low-mids. Its fast transient response makes it a reference choice for acoustic guitars, drum overheads, strings, and piano, while its high SPL handling allows it to take on aggressive acoustic sources without harshness or distortion.

The Soyuz 013 FET is one of the finest small-diaphragm condenser microphones on the market today. Offering the fast transient response of an SDC alongside the warmth, transformer depth, and silky top end typically reserved for vintage large-diaphragm condensers, it is an indispensable tool for tracking acoustic instruments, drum overheads, and orchestral strings.

From Soyuz Microphones

The Soyuz 013 Small Diaphragm FET Condenser Microphone, primarily sold in matched pairs with cardioid capsules and -10db pads – though available singly and with multiple capsule patterns, is the newest member of the Soyuz family. In a break from tradition, the SU-013 is available in both Soyuz signature cream and brass and in black, for applications requiring a less visually conspicuous appearance.

The Soyuz 013 FET features a carefully designed, low-noise Field Effect Transistor topography and the rich sound of custom in-house created and crafted toroidal transformers.

 Sound: 

The 013's classic internal transformer design creates a detailed sound that is robust in the lower frequencies, rich in the midrange, and silky smooth in the upper register.
