KEY HIGHLIGHTS

Capture Classic Sounds, with Modern Flexibility:

Vintage U87 mics are known for their presence, but can get strident when pushed. The 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 Bock187 mic gives you the “golden unit” tone of an iconic studio staple.
