The UA Bock 251 is Universal Audio’s flagship multi-pattern tube condenser microphone, handbuilt at the UA Custom Shop in Santa Cruz.

Going beyond the famed ELAM 251, considered by many to be the greatest vocal mic ever made, this David Bock-designed masterpiece features hand-sourced components for rich vintage sound with enhancements for performance and consistency.

Add Handmade Magic to your Studio

The UA Bock 251 is David Bock's loving interpretation of the classic 251 microphones he studied and maintained as chief technical engineer of the world's top recording studios for two decades. Hand built at UA’s Custom Shop in Santa Cruz, California, the UA Bock 251 mic puts "golden unit" sound at the heart of your recordings.

Rich Tube Mic Sounds, with Updated Sonics

With its German-made CK12 capsule and large output transformer, the UA Bock 251 gives you extended low-frequency response down to 10 Hz and higher SPL capabilities versus vintage 251 microphones.

Built for a Lifetime of Harmonious Recording

Handwired using premium components, each UA Bock 251 is built and tested to David Bock's exacting specifications. With its vintage-inspired case, robust shock mount and accessories, this mic spares no expense to last a lifetime.
