I still find myself saying that alot but I can almost get the sound I want now with minimal trouble these days. First thing I sit in the mix and many others find it very helpful. The bass drum. start stacking on top of that. Bass drum,bass guitar,rythm guitar snare,vocals then I add things like toms, hi hats etc. I also now keep a mind ahead of time towards things like I have learned from experimenting quiet alot. Like I know I like to start slopping the guitar bottom end away around 250-200hz. Then I totally kill it most times at 150hz. Gotta make room for the kick drum and bass guitar. There a few good starter rules of thumb to get a mix working.
well considering that when the old approach existed, i basically knew nothing about mixing and just changed random levels until it sounded ok to my inexperienced ears at that time. i started doing research and reading different sources, and i realized i had no idea what i was doing
