Matching pair of AT813 condenser super-cardoid mics. Made in Japan, this was a great period for AT mics IMO. These require a AA battery, accesible by screwing off the head (won't use phantom power) and have an on/off switch. Metal casing, quality sound and construction. I've used them in my home studio for just about everything and was my favorite vocal mic. A few scratches from handling but never abused.
