$12k is a shitload more money than what I had to spend. If you've got $12k and a space to use.........you can do a pretty nice home rig.
Does he realy need to spend this amount of money to achieve what he really wants to do?
If you are a musician you can get away with spending alot less then 12k to achieve your results
A member of bbs Erland just used
a boss br532 and a shure 606 and he recorded quite a nice guitar and vocal piece which stood up quite well many people heard it and praised his efforts now he
didnt have the budget you have but he still used what he had and took his equipment to its limits an came up shining.
If you are not making money in this industry forget the big dollar outlays as you will never realise enough work back to pay you back for all that hard earned money being spent now.
Start simple buy some good reading material read and understand its contents get intrested in this its your ticket to mixing with others at least information wise so when you ask questions you have something to base it on not just saying hey guys what the latest greatest mic etc forget this way of doing things all it will get you is empty pockets.
Start small be humble and learn and read all you can ask questions but forget the gear comparisons for now none of thats going to make you a great engineer.
If you must have gear ask yourself what do you need gear for are you just doing your own demos or are you doing demos for others or even bands.
All this info is important because the wrong info will lead you down a path buying the wrong gear.
I think you should really sit down a moment and write out what it is you want to achiece first
once you have done that come back and share that info and then decide what you need after that iam sure once all this is realised you will have a great deal of money left
spend some with an engineer and allow him/her to sculpt your sound for you then take this away and really decide then if you still want rooms full of gear.
start small get big on information not big on gear information will set you free to allow you to then achieve miracles with very little all rooms full of gear will do will run you broke remember are you earning big dollar in this industry?????????
If not start to take a different approach the bigboys need alot of this gear to pull clients alot of them are names big guns the equipment really only rounds of a package and you know what the package is them and what they know this is the package not their rack of neve mic pres or their pulltecs or neumanns
without their know how all this gear may as well have stayed in the shop take the hint before you loose all your money mate there are easy ways to get where you want to go but you must employ some thought to get there silence will take you far look listen and learn
