Te pongo unos cuantos párrafos al respecto que he ido copiando con el tiempo, espero que te sirva de algo.

Remember, what sounds good solo'd often gets lost in the mix.
------------------------------------------------------------------------
My livingroom sound gets lost in the mix. What actually works is this obnoxious growl that sounds horrible in the livingroom and awesome in any room. Kinda ckacidy., higher than I like but just fits in all the situation I play in
------------------------------------------------------------------------
Bassist must compete with their best foot forward; clear, fat fundamental tone enriched with some clean midrange and not much else. Trying to poke through the mix by boosting mids and highs won't clear up the bass part since the upper content is mostly finger noise, sympathetic ringing from adjacent strings and buzz or hiss.
------------------------------------------------------------------------
The more power your amp has, the cleaner your tone will be, even at lower volumes.

How to get a good and clear sound from the PA/To the sound engineer?
IME there is two factors to consider for this particular question:
1- It all depends on the size of the room/PA and the "garbage" coming from the stage.
If you play in a room where the PA fights against the stage volume, chances are very high that the overall sound will not be good if point #2 is not respected.
2-Your sound has to be set according to the rest of the band.
If all guitars, keys, bass has a full spectrum sound and everybody plays together all the time => good luck!
No soundman will be able to do anything.
------------------------------------------------------------------------
I strongly encourage bassists to use their rigs only as a personal monitor.
------------------------------------------------------------------------
My approach is to provide myself with what I need to play while minimizing how much I'm driving the stage and room by elevating my 4x10 to waist level and staying close to it. That minimizes interference with the rest of the band or the sound engineer any more than absolutely necessary, while providing a great tone to the PA via my preamp's DI. Most bassists drive the stage like the PA doesn't exist.
------------------------------------------------------------------------
No matter how much you try to perfect "your sound".....once the rest of the band starts playing at a gig, ten feet past the stage no one will be able to tell the difference. And past the ten feet, it will depend on what the soundman does to your bass signal.
------------------------------------------------------------------------
Bad sound, frequently Guitar players with too much low end and bass players with way too much high end on attack or bedroom tone turned up too loud.
------------------------------------------------------------------------
I have come to the conclusion that reducing a large amount of low end on my stage rig (everything below 100hz), helps me hear what I am playing SO MUCH BETTER. Pumping out a large amount low end on my stage rig is not helpful especially since low end (150hz and below) is omni directional and the combined lows of my rig plus the subs - equals a very muddy tone. Boosting anywhere from 200hz to 800hz and cutting the lows 100hz and below has been key to hearing what I am playing clearly.
