Telefunken is steeped in history and this microphone is no different. It's a beautiful all valve pencil condenser which will make your acoustic guitar sing. Prior to 1959, TELEFUNKEN GmbH distributed Neumann GmbH microphones throughout the world. When Neumann GmbH decided to take their distribution direct, TELEFUNKEN GmbH commissioned Austrian company AKG Acoustics GmbH to produce a series of 5 microphones. This series of microphones was comprised of the famous ELA M 251, the ELA M 250, the stereo ELA M 270, and two small capsule microphones, the ELA M 260 and the ELA M 261.
