Here's an AKG D88 Stereo Dynamic Microphone from the 1960's! This one has been modded with two bi-directional 70's Beyer headphone drivers, which makes this a unique permanently set Blumlein dynamic microphone. Beyer's headphones have been used for a variety of different microphones, and the drivers are some of the few with a true bi-directional pattern. This microphone is bright and aggressive, and will make for a nice room option for a variety of sources. If you're looking for a truly unique (and one of a kind) dynamic microphone, this is the one for you!
