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 microphone system comes with a multi-pattern M 903 power supply, M 803 tube microphone cable, ZC03 shell case, M 703 shockmount, M 782 standmount and microphone sleeve.
