Do it all with a classic mic that never leaves your mic stand. 

The UA Bock 187 is Universal Audio’s large-diaphragm FET condenser mic, built to give vocals and instruments the classic tone of the legendary U87,* with modern sonic enhancements by mic designer David Bock. 

Hand built at the UA Custom Shop in California, this boutique cardioid condenser is destined to be the cornerstone of your studio for years to come.

  • Premium large-diaphragm cardioid FET studio condenser mic, lovingly handmade at the UA Custom Shop in Santa Cruz, California 
  • Iconic, "golden-unit" mic sounds with modern enhancements by David Bock
  • Minimalist Class A FET circuitry 
  • Large Cinemag output transformer for rich bass and increased low-frequency headroom

Capture Classic Sounds, with Modern Flexibility
Vintage U87 mics are known for their presence, but can get strident when pushed. Our UA Bock 187 enhances this classic design with a larger transformer, refined circuitry, and a unique "fat" mode that delivers a boost between 10 Hz and 400 Hz. This translates into more dynamic range, presence, and fullness on vocals, guitars, and more.

Add a Handmade Masterpiece to your Mic Locker

The UA Bock 187 is David Bock's inspired take on the legendary U87 microphones he studied and maintained as chief technical engineer of the world's top recording studios for two decades. Handbuilt at UA’s Custom Shop in Santa Cruz, California, the UA Bock 187 mic gives you the "golden unit" tone of an iconic studio staple.
