Well,
In answer to Macle and Jusum, my gear is about as stripped-down and simple as it gets. There's the mackie board > m-audio sound card. I monitor with a couple of Hafler m5's through a 30-year old home stereo receiver. The highlight of my gear collection is a mindprint d.i. port (used to preamp drums and overdubs), and a Joemeek vc6q (electric guitars, vocals). You'd also think I raided Harvey G's "mic locker B" with all the oktava mc012s, cheapo Marshalls, and the sm7.
The challenge about this particular group was in all the conflict going on with some of their instruments. Looking at the spectrum analyzer, one of the guitarists was peaking out consistently at 200 hz. That's snare drum territory, and a guitar has no right peaking there unless you're playing death metal.
Both of the guitars and the keyboard all wanted 2,000 hz. They also all wanted 159 hz, which the bass was stubbornly staking claim to. The keys actually wanted ALL of the bass' and both the guitars main freq's.
What a mess. You could eq some things, but ultimately, that only made them sound unnatural if I went overboard. Their guitar tones were way too driven; too many big muff pies, fuzz boxes, driven tubes, etc. To the point where it made them sound kinda' undefined, lacking in dynamics, and indestinguishable from one another. Ironic how that works.
The band's input was key during mixdown. They seemed to have unusually good ears, and knew what they wanted. And they were good at communicating; example: "Put the keys down low with the bass guitar. Put the bass down lower with the kick. Give the kick a chest-thump, etc." And in the end, at least I knew I gave them exactly what
they wanted, which is what it's all about.
Going forward, I explained to them that they're going to want to change the tone of their guitars and keys so they don't get all this midrange battlestar galactica going on during their live gigs.

The pure joy of it all was that they actually
got it., and they're now experimenting with different tones. Gotta' love that.
Wow. So cool to have Macle and Jusum helpin' out with the critiques. I'm honored. Sorry for all the babbling.
