Mic, Line, EQ... Preamps

Finished ML3 but noise is coming and it is more audible when bass mid and treble are at full
but awesome treble and bass i have grounded every thing properly
Dirty distortion is coming when volume pot is at full even though the input mobile volume is low

any way this will spoil the original quality sound of ax-14

Must assemble in proper case;
Must revise power supply quality;
Not to mention proper wiring.
IMHO,
Max.

Hello, sir Mile. I have same problem with my ML3 project. Everything is properly connected and the ground is also in one point. When the volume is full i have big distortion without signal. All potentiometers are B10, i think they are linear like in your schematic, but i'm not sure. Can you response what change we can make to reduce this noise and distortion. Thanks.
