WhiteStrat,
This was sold as a PA mic. It is not a high end EV recording mic but it has it's own good qualities and has been used on many recordings.
For years I spoke through one of these when doing voice over for my radio show. I speak in a real low voice with lots of proximity effect for a Real Blues radio voice. The 664 helps with the breathiness. I still like it for that but I am experimenting with other mics now that I have more mics to experiment with.
My friend, Joe Lee, said he used a bunch of them at Alley Records in Jonesboro back in the sixties and seventies. He made hits with them. He also used a couple of RCA ribbon mics so they were in good company.
The mic stand thread is built in and is just enough off standard to cause problems. I have some silver adaptors that fit it better than screwing directly onto a stand.
It is an interesting mic with some history. EV sold a lot of them because they're everywhere and they can be had pretty cheap. I need to add them to my fifty dollar mic thread.
Oh yeah, theres more info at coutant.org. He quotes Wetzell at EV who says in spite of the fact that they are not really professional recording mics he gets more inquiries about the 664 mics than any for any of the other vintage EV mics. I guess looks can help.
