Is it bad to use EQs to an "extreme" extent? I use that word because of what my friend said about the settings of an EQ on a song we were helping a mix and master. He had something like this, but more a extreme frequency cut at ~75 and ~125 hz.
I didn't think it was a big deal. I do something similar to the image above on a lot of the tracks in my songs (drop levels at ~100 and ~200 hz usually) to make room for the kick and snare. Only difference is mine aren't as intense as the image above, so medium level you could say.
My friend said this was wrong and that EQ curves should be much gentler and curve smoothly instead of sharply creating steep angles like the image below.
Why does he believe that using the EQ like the first image is wrong?
I hope this makes sense to everyone. Feel free to edit and reword.
