Name That Mic #5
Here’s an inexpensive, unbalanced moving coil microphone I bought used. As with many previous pics, the make and model have been obscured but I haven’t removed every clue. If you don’t know this one, take a guess.
Follow this WordPress blog, or via Twitter or Facebook to find out if you were right, and try to guess all of the microphones in this series.

Darn! I forgot about the PE line. Many Shure models were also sold as “Professional Entertainer” variations beginning in 1972. The PE57 was indeed a re-badged 575S. Now you just need to find an A75L lavalier adapter — a cord that allowed you to wear the 575 around your neck.
