TF29 Copperhead

The TF29 is an original TELEFUNKEN Elektroakustik design that has garnered fans for its natural and non-hyped tonality and unparalleled “quality for price”. It’s a workhorse microphone with a reputation of outstanding sonic performance and value, capable of accurately and honestly capturing vocals, guitars, drums, and nearly any other source put in front of it. The Cardioid-only TF29 Copperhead is easily distinguishable from the TF39 by the addition of the Cardioid symbol on the front of the microphone.
