Untested This listing is for one vintage Electro-Voice Model 664 dynamic cardioid microphone. Introduced in the mid-1950s, the Model 664 is famous for its distinct, rugged design, earning it the nickname "The Buchanan Hammer" due to its robust construction. It was originally designed for high-quality public address and sound reinforcement systems, and is now highly sought after by collectors and audio enthusiasts for its historical significance and unique aesthetic. The microphone incorporates Electro-Voice’s Variable-D technology, which minimizes the proximity effect to deliver a consistent tonal quality regardless of the distance from the sound source. Its non-metallic Acoustalloy diaphragm provides a smooth response and is known for its durability against high humidity, temperature, and mechanical shock. This is an excellent piece for restoration or as a centerpiece in a vintage audio collection.
