Meticulously selected parts

Spurred on by the discovery of a sizable cache of new-old-stock Telefunken tubes that were deemed suitable for microphone applications, Telefunken set sail on a 15-month quest to design a great-sounding cardioid-only large- diaphragm tube condenser mic and bring it to market at an affordable price. They experimented with components, selecting only the best-sounding, most stable ones for inclusion in this amazing mic. High-impedance runs were kept as short as possible to minimize noise. They auditioned an array of output transformers to find the one that delivered the most open-sounding and sonically pleasing response. The NOS 6AK5W Telefunken tube and the Lundahl LL1935 output transformer ultimately made the cut, along selected American-designed electronics and overseas-sourced parts. The result - the CU-29 Copperhead - is, however, more than the sum of its parts.

A valued addition to your mic locker

The Telefunken CU-29 Copperhead isn't a re-creation of an existing classic mic design - or even a variation on a theme. With its warm, clear bass, detailed midrange, and a silky high-end airiness that you expect in mics that cost many times more, the CU-29's unique character and rich sonic texture will be a valued addition to your mic locker.


You bet. If you had to choose only one polar pattern for all the mics in your studio, cardioid would be the one. Although we certainly recommend having omnidirectional and figure-8 microphones in your mic locker for tricky recording setups and advanced stereo miking techniques, your cardioid mics will be your "go-to" mics for the vast majority of recording and sound-reinforcement tasks. A great-sounding cardioid tube condenser mic like the Telefunken CU-29 Copperhead will enjoy constant use in your studio.

    Magazine Reviews
    Sound on Sound, September 2011 "If you've been covetously eyeing a Telefunken mic, you can rejoice that the sound is now available for not much more than $1000. This is not a budget mic by any means, but its pleasing tone makes it very competitive in this price range, and a great choice for any dedicated or well‑heeled enthusiast who records a lot of lead vocals." Music Radar, March 2011 "The CU-29 Copperhead is a classy performer that will capture a transparent and articulate sound."
