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.
