The Telefunken CU-29 "Copperhead" Tube Microphone, is a large diaphragm valve condenser with a directional cardioid polar pattern. The CU-29 is part of Telefunken’s R-F-T Series of microphones, that have been re-engineered to replicate rare and historic microphones, utilising materials and technology available today. The CU-29 has been designed from scratch, and after a tireless process of testing and development, they are now all manufactured in the USA. The CU-29, or “Copperhead” microphone, has an intimately detailed and crisp top end, balanced beautifully by it's rich, warm low frequency response. It features a single membrane model of the TK67 capsule found in the Telefunken AK-47 mkII.
