Bock 251 Tube Microphone Review - David Bock Design | Tape Op Magazine

tapeop.com

The Universal Audio Bock 251 microphone is a triumph of vintage flair with modern versatility. While it nods to the revered Telefunken ELA M 251, it crafts its own identity with a full-bodied low end and smoother upper mids, making it a dream for vocalists and acoustic instruments alike. Its formidable SPL handling and natural proximity effect offer dynamic range and clarity. Although some purists might balk at its sonic deviations, these tweaks grant it a broader application palette. At a fraction of the price of its vintage counterparts, it's a compelling choice for studios seeking that classic vibe with a twist.

Universal Audio Bock 187, 167 & 251

soundonsound.com

Universal Audio's Bock 251 microphone is a blend of vintage inspiration and modern craftsmanship, boasting exceptional build quality and an impressive sound profile. With a nod to the iconic Telefunken ELA M 251, it delivers a robust, natural low-end and a flattering midrange, making it a great all-rounder for studio use. The microphone’s standout feature is its ability to maintain tonal quality across different polar patterns, a feat not always achieved by vintage mics. However, its premium pricing means it's out of reach for many, limiting its appeal to high-end studios. Overall, the Bock 251 excels in combining classic design with subtle enhancements, offering a top-tier option for those who can afford it.
