yeah Im not sure I can agree with that, so I will just try to answer the title question and maybe that will help
this eqing seems pretty standard for this sound: the lows are boosted to fill the low end a bit more, the mids are scooped to avoid muddy, the highs are boosted so the bass is not lost in the mix
with this sound it is the highs that give the presence not the mids…it is less grunty more trebley sound than mid boosted but with less mud and the the deep bass to retain the power
Also Butch Vig recorded and then mixed together 3 tracks of bass for the Nevermind album tracks (something like -normal, -played an octave up, and then one played with bass -downtuned very low) so you are trying to copy that with one bass!
It also really depends on the bass pick-up, if you play with fingers or a pick (and how you pluck/pick!!), the number of guitars (and relative volume levels), how much distortion and so on…
Yeah, that might not work well, but it also depends on the context.
There are so many factor to account for, the best way to find what works in your own case is to experiment - yes, it takes time - and listen: first of all to the music but also to other people’s feedback
That depends a lot on the relative volume and the location (or speakers), not only on the bass tone
Here’s something to keep in mind. A bass playing on it’s own is a very different thing than playing in a mix. A scoop will sound very nice on it’s own, but in a mix having those mids will really help cut through the mix and make the bass heard.
Answering my own curiousity here, and I don’t know why I never thought of this before but apparently P Basses are naturally mid forward in tone.
So by boosting mids I’m probably doing too much of it!
This is why I was probably having a tough time with boosting mids because it always made me sound really quacky. Boosting Lows and Highs probably gets me closer to a “balanced” tone.
It should be said that the Dark Glass Tone Capsule, which many people like and you see in some models like the Dark Ray, allow you to adjust bass, mid, and high mid but has no treble control. You adjust clarity through the high mids.
The problem with “rules of thumb” as it relates to EQ in recording or performing live is that for everyone you can present there’s often an exception to it. It’s the reason we all have EQ/voicing controls on our basses and our bass rigs so we can find the best sonic space to fill for that gig or even for a specific song. We need adaptability.
