Handcrafted entirely in the US, the JRS-34-P combines the best attributes of vintage and modern technologies to create a high-quality ribbon microphone ideally suited for music and vocalist. The JRS-34-P, like other passive ribbon microphones, requires a high-gain preamp with over 60dB of gain. Included is a beautiful handcrafted wooden box, designed to properly store the microphone.

Designed in collaboration with Stephen Sank, the Cloud ribbon mics were given the model number prefix JRS in homage to the late Jon R. Sank, Stephen Sank's father (1934-1998). Known for his work with RCA* that produced legendary microphones such as the BK-11 and BK-10A, the senior Sank succeeded RCA's Harry Olson as the guiding force behind the company's continuing development of ribbon microphones. Having studied alongside his father since the age of 10, Stephen Sank's efforts in conjunction with Cloud build upon this same legacy. Each JRS-34 ribbon is cut, corrugated, and installed by hand in precisely the same fashion as prescribed by Olson. New ideas expand the performance capabilities of the blueprint as well, bringing the design into the 21st centruy with the addition of audio transformers by CineMag Inc., neodymium magnets, and more.
