Overview

The original Telefunken ELAM 251 is among the most coveted microphones in studio history — sought after for its silky top end, three-dimensional presence, and effortless way with vocals. Original units now sell for tens of thousands of dollars when they appear at all. David Bock has spent his career studying and maintaining these mics for the world's top recording studios; the Bock 251 is his definitive recreation, built using a German-made CK12 capsule, NOS ECC85 tube, and Cinemag output transformer.

Why a Bock 251?

It's the mic engineers reach for when nothing else is quite right on a vocal. The Bock 251 brings that sound back into reach: hand-built in California by people who care deeply about getting every detail right, with modern enhancements like switchable Fat mode that the originals never had. It's an investment in a mic that will outlast every interface and DAW in your studio.
