Here are three Electro Voice RE10 dynamic microphone pairs from the 1970’s (3 matching pairs available at $500 each)! RE10’s have little to no proximity effect with great off axis rejection. These are versatile dynamic’s that excel on toms and acoustics, but make nice utility microphones on various studio sources. Three separate factory pairs are available, each pair with matching serial numbers that were made in the factory together and sold as a pair. It’s rare to find a pair of these microphones that have stayed together over the years! The RE15 / RE10 models feature the same design and internals, though the RE10’s are better in situations where unit to unit matching isn’t necessary (which is funny given these were sold as matching serial # pairs). RE10’s give you a very similar sound to the RE15 for half the price. These microphones are functioning perfectly with some minor signs of wear from use over the years. Each pair sounds identical and is in great condition! Grab one of these rare matching serial # RE10 pairs from Electro Voice!
