Our take on the Universal Audio Bock 251 Large-diaphragm Tube Condenser Microphone

The Universal Audio Bock 251 is a large-diaphragm tube condenser microphone built with David Bock, modeled on the classic ELA M 251. It uses a single cardioid pattern, a tube circuit and a CK12-style capsule, and it is aimed at studio vocal and instrument recording rather than home setups. It is a premium, single-pattern tube mic, so it competes with other boutique 251-style recreations and with multipattern tube mics that offer more flexibility for less. Reviewers treat it as a vocal-first microphone with a smooth top end and rich low mids.

What reviewers say

Engineers describe the Bock 251 as a vocal microphone first, with a silky top end and a thick low midrange that needs little EQ. Owners praise its build and its resemblance to the original 251 sound, while some note the single pattern limits it for room or Blumlein work.

Questions and answers

Is the Bock 251 good for vocals?
Yes. It is designed as a vocal-first tube condenser, with a smooth top end and full low mids that suit most singers with little EQ.
Does it have multiple polar patterns?
No. It is cardioid only, so it cannot switch to omni or figure-8 for room or stereo recording.
What do I need to use it?
A preamp with enough gain, an XLR cable, a sturdy stand and the included tube power supply. It is not USB and has no built-in controls.
How does it compare with the original ELA M 251?
It is a modern recreation built with David Bock, using a CK12-style capsule and tube circuit to approximate the original's sound rather than replicate its exact parts.
Is it good for acoustic instruments?
Yes, especially strings and acoustic guitar, where its smooth top end and body work well. Its single cardioid pattern limits some close-miking options.
