Product Description

In 2020, Universal Audio enlisted David Bock of Bock Audio to design a new line of premium tube and FET condenser microphones based on his most cherished designs. Manufactured in Santa Cruz, California, the Universal Audio Bock 251 is a large-diaphragm, multi-pattern tube condenser microphone built with high-quality through-hole components and timeless UA design for the professional engineer and recording artist.

The 251 has become a Holy Grail microphone due to its incredible tone, and has been used on countless great recordings over the last 50+ years. It is also one of the most-replicated microphones in history, a testament to its enduring status as a piece of immortal gear. The UA Bock 251 builds on this legacy as an authentic replica made with premium components for ultimate reliability. The transformer has been re-engineered for a wider frequency response and greater headroom. Like the original, the Bock 251 also features switchable cardioid, omnidirectional, and bidirectional (figure-8) polar patterns for maximum versatility in the studio. It ships complete with a shock mount, power supply unit, 20’ cable with Tuchel connectors, a signature wooden box, and retro-style suitcase. Add the Bock 251 to your mic locker today and use it to capture astonishing vocal tracks or for detailed recordings of any instrument!

FEATURES:

  • Trust your sound to a premium studio mic, lovingly handmade at the UA Custom Shop in Santa Cruz, CA
  • Enjoy "golden-unit" consistency with every Bock 251 mic hand calibrated by David Bock
  • Get the sound of one of the most treasured mic designs in history, updated and overbuilt to a higher standard
  • Experience boutique UA quality including premium capsules and handwired components to last a lifetime
  • Proprietary all-brass C12-type capsule
  • Switchable cardioid, omnidirectional, and bidirectional polar patterns
  • Newly engineered transformer for increased frequency response and headroom
  • UA Bock 251 PS true linear inductor-based power supply for increased dynamic range and tube life

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
