well you ain’t wrong there, also it’s called EasyEffects now and only works on pipewire, pulseeffects still exists for pulse but as PulseEffects Legacy.
I don’t see why qpaeq would be harder to use than pulseaudio-equalizer-gtk though. They’re both just simple equalizers.
I do have a little (big) tip though.
Pulse/EasyEffects may be advanced, but if all you want is an equalizer it can do that quite easily, even if perhaps it’s a bit overkill for that.
However there’s an important reason why you’d want to use Pulse/EasyEffects. It has more than just an equalizer, and it also has plugins for microphones (particularly noise reduction and echo cancellation)
For your output however it has a lot of effects I don’t really understand, + Bass Enhancer, which I understand very well, and it does something to your bass that an equalizer just can’t manage by itself.
Lastly, the hardest part of getting good sound is configuring it yourself (or learning how), even if all you use is an equalizer, most of us don’t even know which slider does what in an equalizer.
With Pulse/EasyEffects other users have already done the heavy lifting for us 
We can just download their presets instead of learnign how to do it on our own from scratch and mix & match until we find the perfect preset.
If you actually try it, you’ll probably never wanna go back to using just an equalizer again.
Edit: Wow, also, funniest thing, I apparently posted a comment on this tutorial about a year ago 
I have since tried qpaeq, I did not have the same issues with it as I did with pulseaudio-equalizer-ladspa & pulseaudio-equalizer-gtk.
