I am doing sound for a friend's band on a semi-regular basis, and
the mixer their regular gig provides is of, mmm, marginal quality.
So, I proposed to them that I try to build us one, and I am
curious to know if anybody knows of plans for a good, clean, DURABLE
mic/line audio mixer, for live use with a separate power amp. I have
poked through back issues of R-E and popular electronics, to little
(not entirely no) avail, and all the plans I see in my books are
a bit primitive (read: circa 1970's.) Ideal features would be:
switchable stereo/mono operation
2+ fx or tape loops
monitor out
meters on each channel
and clean enough to be used, in a pinch, for recording.

is there an FTP site with bunches o' plans I could peruse?
is there a good book I don't know about that has all my answers?
is there a good-natured EE in the Mpls/StPaul area who tosses this sort
of thing together in their sleep?

Vielen Dank for any help or hints.

(the band is a nifty techno-pop trio.. guitar, bass, singer,
an Amiga and a wall o' keyboards. /Cafe Fnord/.. if you're around
the Twin Cities, look for them.)
