Its the same for everyone and I think it’s the way a good eq should work.
From what I understand, when you activate the custom eq, the volume is actually decreased for every frequency range. The frequencies for which you set a positive value will less be attenuated than others set to 0 and much less attenuated than frequencies for which you have chosen a negative value.
I believe the purpose of this is to avoid additionnal clipping (if the music you listen to already has clearly audible clipping) you might get if you increase some frequencies.
Just increase a little the volume of your fuze to get exactly what you want.
