Telefunken Alchemy Series TF 29 Copperhead


TF29 Copperhead

The TF29 Copperhead is an evolution of the CU-29 Copperhead, an original TELEFUNKEN Elektroakustik design that garnered fans for its natural and non-hyped tonality and unparalleled “quality for price”. The TF29 continues this reputation of outstanding sonic performance and value. It’s a workhorse microphone, accurately and honestly capturing vocals, acoustic and electric guitar, drums, and nearly any source put in front of it.

Circuit Design
The TF29 features a new old stock American-made 5654W vacuum tube, all-brass K67-style capsule, and a premium Swedish-made Lundahl output transformer. These components create a balanced frequency response and natural tonality, making the TF29 a trusty go-to choice.
