Geez, we're going to cause him to never touch an EQ knob again.
You can do everything right: arrange, get the gear, have a nice room, etc. and still need to EQ to clear up *some* inevitable mud, especially when you obviously don't have ideal situations. But yes, there's a diff between fixing mud (if you're referring to it that way there is something severely wrong with the transparency of your monitor, gear, performance or room... don't pick on the helpless li'l mix) and making things "righter."
*You* may still need to use panning and reverb to reinforce the space of the mix, for one, regardless of how amazing the arrangement and particular the space, performance and equipment is. No matter how "true to sound" your input collection and then output is, you still have some work to do with the mix to make it match the space and feeling of being there, which simply may never truly be duplicated save for a change in one or more of the aforementioned.
So yes, while there are a lot of truisms in the thread there are also plenty of generalizations to go along with it.
That is clearly lightyears beyond covering a wellmade song as you're setting out to do.
Not everyone has access to a space with zero effecting of the sound, monitors that are completely flat and transparent, high quality this or that, etc. So you can not make music until you "are ready to make good recordings" aka specific gear, treated rooms monitors etc.... or you can roll up your sleeves and try to mitigate what is going on with your particular mix.
The reality here, and what Daisy is guiding your towards, is that if you're standing there in a room and you hear the band play live, why would you then try to fight those sounds by aggressive effecting or EQing if you mean to capture and replicate that sound? There are reasons to do it intentionally if you're going for something special, but you're either grabbing the sound or not.
Just because you're hearing a dampened version of the sounds or that you're hearing them individually doesn't mean you can simply overlap them in a mix and tweak knobs to get them friendly...
...one of the most telling things when I was first starting out is looking at people's sample mixes that sounded great, their source files and how their EQing was very, very, very, very, very, very minor. When someone says cut this or that out to bring something else up it is so slight that it really is a simple shifting of a layer in the mix at that frequency. Really, most of the times I couldn't tell much of a diff between the two, but you really can hear it across a wide variety of listening devices.
Sure there is always room for notching out certain bits and of course low and hi passes where needed, but the less, the better. Some folks hardly even EQ at all until the "mastering phase" which is really mixing the stereo track to make room for some extra loudness or bringing a bunch of tracks to a similar feel/level.
It cannot be emphasized enough that you begin with the actual sounds that are made by your gear, which are embellished by their environs and then further embellished by the microphone, preamps, and hardware until it is recorded. If you had masterful control over placement, and how each of those segments in your chain effected the sound, you could easily mitigate them.
An SM57 colors a snare differently than a Beyer201. Do you just leave how they alter the sound of the snare alone? That's where you come into understanding that microphone selection is one of the first (after where the instrument is placed in the room and how it is played) choices in terms of 'eqing your song.' Next would be the position of the mic itself. The SM57 boosts high-ends. The Beyer adds a midrange bump. If you had the choice, you'd pick one or the other not only for their specific coloration, but also for what EQing choices you have in terms of bleed, isolation and lowering transients. Making use of the proximity effect of the beyer as well as its superior off-axis rejection is why people use it for%
