Thanks, Jay. I am using a mike preamp. (I have to, because it has to

phantom power), but I can't drive the chorus unit directly, because when I
do, the sound is badly distorted.
WAIT! STOP!
You didn't mention that before.... we all assumed you were using a phantom
supply. So now you have a preamp with a line level output going into a
pedal that expects an instrument level output.
This is, (I think) because the mike
preamps have low impedance outputs and all these chorus pedals are made
for
guitars, and take high impedance inputs.
It's not the impedance it's the operating level.
I can screw around with
potentiometers to reduce the drive power of the preamp output, but I was
hoping that someone would know of a chorus unit that was made for singers
that would accept a low impedance input. I already have a rack unit that
works OK, but it is too big to be convenient at gigs.......I am looking
for
a pedal that will do the job, or one whose input I can modify to get it to
work OK.
I don't know of any "vocalist pedals." There are lots of fine rackmount
effects units that can do a chorus. I suppose you might look into the
old Alesis Wedge or Nanoverb, which are physically very small.

Not all chorus effect units are the same....In fact, my Beranger 45 watt
keyboard amp boasts a chorus effect, but it is, as far as I can hear,
nonexistent. I bought a unit made by Audio Technica that sounds great when
applied properly, because my friend has one and I liked its sound, but he
uses his with a guitar, and I want to use mine with my horn. I think my
problems are just signal level problems, and all I have to do is find and
install the right attenuators.
