Here's a Shure SM57 Unidyne III Dynamic Microphone from the 1970's! This is the very first version of the famous SM57, back when these microphones were fully manufactured in the USA. This microphone has all of the characteristics of a modern SM57 with the added natural depth of the original version. This microphone will prevail over a modern example due to the higher quality in parts that Shure used back in the day. This microphone has some wear to the paint of the body, but is working perfectly. Grab the original 1970's version of one of the most popular mic's ever made!
