Offered here are these classic vintage microphones, standards in most top studios. Abbey Road has over 20 so enough said. Will accept other capsules so can be turned into omni and also speech cardioid mics. These work great on most things, especially acoustic instruments. Fantastic detailed, warm sound with great off axis response. The mics work well as a pair with similar outputs and sound. Both capsules were cleaned . I accept returns so if you are not completely happy, send them back.
