Get Iconic Sounds with Modern Tone Sculpting
Vintage U67 tube mics are cherished for their full sound and lively midrange. Our UA Bock 167 improves upon this classic design with three EQ filtering options, a unique "fat" switch for boosting between 10 Hz and 400 Hz, and continuously variable polar pattern. This translates into recordings with more dynamic range, tonal extension, and flexibility.

The UA Bock 167 is David Bock's thoughtful reimagining of the iconic U67 mics he studied and maintained as chief technical engineer of the world's top recording studios for two decades.
