Going beyond the famed ELAM 251, considered by many to be the greatest vocal mic ever made, this Universal Audio David Bock-designed 251 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 10Hz 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 shockmount and accessories, this mic spares no expense to last a lifetime.
