I’m from an artsy family and chose drumming to pursue, in my world EQ-ing is never used. Artists use paint musicians use sound to create atmosphere and rhythm. Don’t erase the artists vision with random EQ experimentations. An engineer and artist worked very hard to sculp the sound they present....don’t tag it with EQ.
So lemme ask you this...
Hypothetically speaking, pretend you make a song with 2 notes only:
1. B8 on a violin (which is 7.9kHz), recorded at a 10dB level
2. G7 on a guitar (which is 3.1kHz), recorded at a 5dB level (half the volume of the violin note)
Well, let's say I have age related hearing loss, corresponding to a -5dB loss at everything above 7kHz. I'm not hearing your song as you intended, because I am hearing both notes at the same volume. To truly hear your music as you intended, I need to use EQ and add +5dB above 7kHz. THEN (and only then) will I hear your song as you intended.
Make sense?
Now take that same example, but instead pretend I have no age related hearing loss. However, in this example, I am using a set of headphones that have an odd tuning by the manufacturer - an artificial spike of +5dB @ 3kHz. When I listen to your song using those headphones, I am still not hearing your song as you intended. The guitar will be the same loudness as the violin, because it is being artificially boosted/colored by the headphone tuning. The good news is that I can use EQ to reduce the 3kHz spike by -5dB. Then, and only then, would I hear your song exactly as you intended.
See the value of EQ now? Most of us don't generally use EQ with the intent of "messing up" artists' music. Rather, most of us use EQ to correct flaws in our individual hearing or to recalibrate gear that has been artificially colored by manufacturers.
