I am trying to EQ my iPod to an Oratory1990 preset for my headphones. I did this on my computer using PEACE and I really like how it sounds, however I have been unable to replicate this on my iPod because the preset uses two high shelf filters. Is it possible for me to replace one of the peak filters with a high shelf? I would be willing to try to learn how to edit the source if it is possible to make this change or if someone has tried it already.
I've attached the preset that I'm trying to use if anyone has any suggestions.
