As you may know, the 664 and 666 were EV's first "variable-D" mics --
the 666 was the pro version, the 664 for "PA." The 666 was known as the
Buchannon Hammer because Lou Burroughs, co-founder of EV with Al Kahn,
demonstrated their ruggedness by using one to drive a nail. (EV was in
Buchannon, MI; Lou taught workshops on microphones, and wrote a great
text on their use.)
Directional mics have "proximity effect" (bass boost when close to the
sound source) that results from their construction -- front and rear
openings to the capsule that cancel sound from the back of the mic.
Variable-D mics have almost none by virtue of one or more additional
openings along the "handle" of the mic. The EV RE16, RE20, and RE27 are
variable-D mics.

Jim,
In the 1960's I had an EV664 which I used on 2m AM 150w plate
modulation. Made very nice AM with my Johnson 6N2. Mic sat in
storage shed too long and suffered moisture corrosion.
