While in college, I had a job for awhile at KPFA [FM] in Berkeley CA. 
They had one of those old RCA "velocity" mics [the sort of 
prismatic-shaped ones, fairly big] on the control board and one of my 
shifts was to sign the station on the air at 0600.  I discovered that, 
if I crawled right up to the mic while reading the sign-on script, I 
could sound like Johnny Cash instead of a 17 year old.  The effect was 
striking.  I think it's true of most mics, this one was just extreme.

I use a Heil Elecraft ProSet with the electret mic.  My "Audio Elmer" 
[K9YC] suggested setting the TX EQ:

0.05 -14
0.10 -10
0.20  -6
0.40  -2
0.80   0
1.60  +4
2.40  +6
3.20 +10

In SSB contests, if I don't get at least six unsolicited comments of 
"great audio," I'm disappointed.  It happens all the time.  Of course, 
I'm no longer 17 either.  One of these days I'll have to get Rich, NU6T, 
to trade stations with me and listen to it myself.
