sounding like a teacher: try to avoid thinking in such imprecise terms.
your analysis seems to imply that the midrange needs boosting.
from what you described above, it's evident that the midrange is ok (the
room even has a tendency to boxiness), it's just that the smilie-shaped
main eq will over-emphasize bass and treble. so the way to tackle that
is _not_ to boost the mid-range, but to correct the crooked curve on the pa.
i honestly don't know why a 30-band eq lets you boost stuff. 99% of
users would be much better off having an eq that only provides attenuation.
> - Bass (thats me) no PA, (not by choice, but what's practical) Amp eq not
makes sense, unless you have a little headroom on the pa and a guy at
the controls during the show, in which case it's nice to reduce the amp
volume a bit and give him/her a few dbs of actually working with the
bass (for me, even as little as 3db SPL raise over the amp sound gives
me a lot of freedom to shape the sound). plus for the house sound, heavy
compression on the bass is often useful, and bass players are naturally
reluctant to use it (and they shouldn't, because playing into heavy
compression leads to sloppy technique, so keep the amp unsquashed).
when i have to amplify the kick drum, i will put the bass on the pa as
well. with small speakers, it's very difficult to create a kick drum
that doesn't sound like a cardboard box thrown out of a window, but if
the bass locks tightly, the combined sound can be quite impressive. to
balance that, i need both instruments on the pa.
when i work with bass players in small venues (where most of the house
sound is from the amp), i let them set up their preferred tone, and then
if the amp has a good eq, i will approach them during the soundcheck to
correct house sound problems directly at the amp (again, attenuation
only). often, it's just a few frets on a particular string that are
> It sounds from what has been said, that an omni mic would help vocal two
honestly, an omni mike won't help you. fons does have a point in saying
that omni mikes have some advantages and could be put to good use
outside the realm of classical recording, but until someone sorts out
your lead singer problem, that's academic :)
get yourselves a sound guy to run your show who is thick-skinned enough
to tell the bossman go pee, wait for the audience remarks about how good
the sound was for a change to sink in, and then after one or two shows,
you have yourselves a reference sound which you can try to recreate even
without a sound guy at the controls.

get a mixer with two semi-parametric mids, problem solved. very decent
ones are available nowadays at very low cost. a year ago, i got the club
i work for to invest in a new board (an a&h gl 2800 for about 3k euros
plus taxes, which is really negligible for a professional venue), and
the musicians have been more than happy with it. a board with that
feature set and sound quality would have been high in the five digits 15
years ago. nowadays, there's really no need (and no excuse) to work with
inadequate mixers if you're serious about your music.
> For vocal three, anything has to sound better. She gets
an omni has absolutely no advantage there. your singers will want to
work on their microphone technique and exploit the near-field effect in
a musical way.

shotguns are not useful for music stages. they do have better side
rejection in theory, but at the cost of a very irregular off-axis
response. the few times i used shotguns in the theatre, i found they
would give me even less gain before feedback than a standard
supercardioid, and required insane filtering.
