That looks very promising! I was searching for systemwide EQ apps about a year ago (with the aim of cutting several dB across all frequencies, not actually using it as an EQ) and I don't think I saw that one. I just gave it a try on my 2014 Moto X (which has had weird EQ-related bugs in some other apps) and it worked fine. I was able to make fine adjustments to audio whether it was playing from Firefox, YouTube, or my music app of choice.
