Ciaran, your set up is a good set up; if you're Metalica, and you have a 96 channel board, and 96 rack spaces for outboard gear, a full stage crew, monitor tech, system tech, drum, bass and guitar techs, and a 20,000 seat arena.
It's entirely too convoluted for a 10 piece jazz band that is playing for a few hundred people. Not to mention that the sound that you refer to is not suited to a jazz set up. Heck it's probably not even suited for a funk band. If you mic and mix every band you work for that way, then I don't want to hear you mix.
My approach to sound reinforcement: keep it simple. It's much easier to trouble shoot a one mic, one channel kick drum set up, than a two mic, four channel set up.
Unless you are fully qualified and able to run a set up like you describe, you're just asking for trouble. The problems that can arise with a set up as complicated as yours are virtually infinite. And even if I had the budget, and equipment to run a set up like that, I wouldn't use more than two channels for kick drum just on principal.
But I AM qualified to do it, and I dont need roadies or anything. I designed the rig, built the rig, and now run the rig. I know it inside and out. So dont give me the whole "overly complicated" bit. That to me is a non-sound man trying to make an excuse for not becoming "better educated".
Just because you may not be able to get your head around gear, doesnt mean its not easy for some of us.
Just me and my gear and my friggin DODGE MINIVAN!!! That is paid for...gear and van...by myself, on top of horns, school/student loans and working a 44hr a wk day job (and having a girlfriend!). And I practice 90 mins a day. I'm 24.
I only have a 16-channel board, and its a three piece band, and we would LOVE to play for a "few hundred people" sometime. Usually its more like a hundred, or less.
Its not overkill, its just what I do.
Not using two kickdrum channels "on principle" is arrogant and foolish, imo. But by all means, I encourage people reinventing the wheel!!! I'm just saying if you want to sound "acceptable" do whatever the heck you want as long as it doesnt feed-back and is intelligeble.
If you want to sound great, then learn about live sound. Not what is "easiest". I friggin love live sound man, as much as sax, and have certainly done a lot of it.
And anytime you would have me I would love to mix you and your band. But based on your expressions here "if thats the way you mix then I dont want to hear it..." then instead you can go f-yourself.
How dare you be so dismissive.
I do not mix every band the same way. Bands that want to sound big, huge, tight, and GOOD come to me.
So go work on your tone or play some scales or something. Convince yourself theres some nuiance about your sound that nobody else could possibly understand/work with. I'm too busy getting gigs and partying to write any more of this post.
Except that I love subs in cars.
Big, f-off ones.
