im very much a beginner, and recording music is just a hobby. i'm a businessman, but when i have some extra time i love to research audio engineering and practice in a small home studio i set up. i know that eq'ing is a very very important part of mastering, but i have no idea how to do it. is there a website somewhere that says the basic frequencies to make different instruments sound the best? or do you just kind of have to do it by ear? does anyone have any tips? anything would be great. thanks a lot.
