Your New Go-to Mic

The Telefunken CU-29 Copperhead large-diaphragm tube condenser mic gives you warm, clear bass, detailed midrange, and the silky high-end airiness of mics costing many times more. To deliver such an outstanding price/performance ratio, Telefunken gave the CU-29 a fixed cardioid polar pattern, but this US-made gem doesn't skimp on component quality. Its NOS GE JAN 5654W tube, Lundahl output transformer, and other top-drawer parts give this mic an open-sounding and sonically pleasing response. Want an affordable go-to mic for everything from vocals to drums? Sweetwater's got it: Telefunken's CU-29 Copperhead.

Telefunken CU-29 Copperhead Large-diaphragm Cardioid Tube Condenser Mic at a Glance:
  • Meticulously selected parts
  • A valued addition to your mic locker
  • Cardioid-only
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 GE JAN 5654W 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.

Cardioid-only?

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.

Amazing Microphone

Amazing microphone. It sounds wonderful. High ends are so smooth, lows are there and the mids are powerful and present. Great for vocals and acoustic instruments. Worth every prnny.

Great Mic

I love it and use to preach online and to sing. This microphone gave me a user friendly way to get my message out to the world. I like telefunken's products and the next mic will be telefunken at the higher level.

Female Vox

I bought this mic just because I wanted the Telefunken Brand in my cabinet, I actually wanted the E LAM 251 but couldn't afford it at that point.But MAN !! this mic exceeded my expectations as an entry level mic, I recorded a soul/jazz female singer with it and was blown away with the clarity and depth of the Copperhead!It's my to-go mic for female vocals now.

Different tube, still a stellar mic!

I purchased the Copperhead a few months back and was slightly disappointed to find that it came with the GE JAN tube instead of the diamond base 6AK5W as advertised. I inquired about this through my Sweetwater sales rep, Mark Chapman. Mark went the extra mile and contacted Telefunken. Their response is that they can no longer source the 6AK5W's and have chosen the GE tube as a suitable replacement. I can say that my initial impression of this mic is that it delivers on all claims. It is warm, smooth and needs little to no processing to sit perfectly within a very dense mix. The natural sounding mid bump is perfectly matched to an aggressive male vocal. The top end is clear and detailed but not abrasive like some LDC's tend to be. Though I am bummed that I did not receive the diamond base tube (which to me was one of stronger selling points), I do not regret my purchase and still find this to be one of the best mics I have ever heard. Thanks Mark! Sweetwater is the best for a reason!

Awesome for Voice Overs

I previewed dozens of Mics at the June 2016 Gear Fest. The Telefunken CU-29 was best overall for my Bari voice. I own about a dozen different Mics. This one makes my voice come close to my desired sound of the Bari sax in Tower of Power. Ordering from my Sweeteater Sales Engineer.
