Bock Audio 251 Large Diaphragm Tube Condenser Microphone

Large-diaphragm tube condenser microphone in wood box - includes power supply and spider shock-mount
MFR# 251

Product Description

The vintage 251 is THE vocal sound people ask for, but the original (vintage) versions are 50+ years old and sound very different from one another.  Repairing, rebuilding and “nursing” original 251’s along has been David Bock’s work spanning over 30 years.  The risk for a modern studio or end user to depend on a vintage mic on a daily basis is increasingly problematic.

The Bock 251 is David Bock’s answer to the vintage mic dilemma of getting “that sound” without the headaches.  It is a premier lead microphone for premier voices. It is built to last and provide the studio and user with many years of daily, high end performance.

The BOCK 251 provides the user with absolute confidence that this is the mic you put in the most critical situations.  The BOCK 251 uses a proprietary hand made German capsule, a proprietary hand wound multi sectioned audio transformer, a NOS tube in the mic amplifier, a hand built outboard power supply and a custom low capacitance audio cable.  This is one of the best overall mic packages available on the market at any price.  The BOCK 251 is the ideal microphone to choose when there is a variety of applications that must met with absolute top recording quality.  With frequency response that extends well beyond the normal range of typical studio microphones, the BOCK 251 sets new standards.

For vocals, the BOCK 251 instantly delivers that huge vocal sound you have wanted for years.  It sounds equally impressive on females and males. It will capture the most intimate and subtle details of a vocal yet maintain integrity at high SPL’s.  It holds up track after track, “sitting on top” in extremely dense mixes without EQ. For instruments, the BOCK 251 offers very high end performance on critical stringed instruments, orchestras, choirs and small ensembles.  The outstanding transient response reveals elusive harmonic details that spell the difference between good and great in your recordings.

The BOCK 251 cardioid pattern shuts off the back of the capsule to deliver extraordinary vocals when worked very close.  It is recommended to use a pop filter on less experienced vocalists to enable closer working distances to take advantage of the magical proximity effect.  There is no low frequency filtering used on a BOCK 251 so you will hear low frequency content you’ve never heard before.

At distance, the BOCK 251 delivers a level of definition that is amazing.  The high end does not fade with distance like so many other condensers and the power and depth of the low end response is a joy to hear.  The omni and Figure 8 patterns prove useful in these non-voice applications.

Unfortunately, it's nearly impossible to find an original ELAM 251 for sale, let alone afford one when it comes up! 20 thousand buckaroos for a mic? I don't even have that much Monopoly money!

This is a great alternative for those who want the legendary sound without the legendary price tag.

Sounds great on almost anything. Vocals, overheads, acoustic instruments, room mics for a drum kit, etc. Even a kazoo will sound silky smooth and pristine on this bad boy. When comparing it side by side to an original it really comes down to whether you say potato or potato (different pronunciations).... It's a modern take on a classic. The sound is a little more on the bright side to my ears. David Bock really didn't take any detours while creating this modern classic. Astounding ingenuity.

What are you waiting for? Buy the Bock 251 and start spreading that Miracle Whip today!

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.

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.

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.
