“The TF39 Copperhead Deluxe is an expansion of the “Copperhead” sound with the addition of a dual membrane K67-style capsule, allowing for 3-pattern selection between cardioid, omnidirectional, and figure-8. This added feature set gives the TF39 greater flexibility and options in the studio. Sonically and component-wise, the two microphones are otherwise the same.
The TF39 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 TF39 a trusty go-to choice.
Every TF39 Copperhead Deluxe Stereo Set system comes with two sonically matched microphones, a variable pattern dual M 901S Power Supply, (2x) M 803 Tube Microphone Cables, (2x) M 703 Elastic Shock Mounts, (2x) Microphone Sleeves, and a Locking Flight Case. All the electronic components in each system are matched sonically and electronically, including matched capsules, transformers, and vacuum tubes.
