graphic equalizer problems

[u blighter]

hi i recently got an s4 & i like it apart from one thing. when i turn the on any graphic equalizer ( i`ve tried them all) it makes the sound worse instead of better. is there a fix for this? it must be a problem with the android software as the same thing happens no matter with external equalizer app i use.

I know you can set a custom equalizer by default and adjust the levels. Have you tried that?
