Hi.
The sound doesn't change at all.
No one change.
I can move the dial.
The curve mapping changes when i move the dial.
Equ,Tone,Limit are enabled.
Bass,Reverd,Tempo,Stereo,etc works fine.
In no one divice it works.
6 or 7 divices.
Directly on the phone,it even does not work.
Only Treble does not work at all.
