Electro Voice vintage microphone EV-664 Untested with the EV-419S base with push to talk or stay in talk position switch. I added this mic to my collection a few years ago. It is time to reduce the collection. I have never tested the mic and was used only for display. The mic is in very very good condition. There are a very few very slight rub marks on the base and very few very slight scratches on the mic base. The screen grill is straight with no bends. No dents on the mic. No corrosion on the mic. This mic was a favorite of Ham radio operators. Very hard to find a 664 mic in this condition, most have seen hard use and show it!
