I noticed that too on my B3.
Some effects induce a big change of eq. It can be a huge mid hump or scoop or a big cut in the lows. So I don't use it anymore with one effect I engage or cut.
I create 2 adjacent patches with for example a comp and an amp sim.
In one of the 2 patches I add the effect I want and then adjust the eq of the amp sim to get a global tone that sounds right to my ears when I compare it to the patch without the effect.
Hope it makes sense for you.
A great tool if you want to use only an effect that you engage during à song when you were playing without any effect is to create an empty patch and then another patch with the effect + the AcBsPre to eq it right. The AcBsPre is very complete to shape a sound.
