I'm having a lot of trouble with my guitar and bass tones. I feel like this is a large area I struggle in. Listen to this mix I've recently done (some of the playing at parts lacks tightness I know, I threw it together in a day) https://dl.dropboxusercontent.com/u/6010620/MIX TEST MAN.mp3 The problem I'm having is determining how much bass/guitar I need in my mixes, and specifically how much highs/presence I need in my mixes. When I hear other mixes in the Practice Room by accomplished mixers, the guitars just sound different for some reason...like the bass has this tone that is controlled but present and the guitars sound smooth and big not fizzy and thin like mine. Basically, why do my mixes suck? Can someone explain to me what I am doing wrong? My mixes simply don't have that character.
