Aight so this mod is self explanatory, and also this is my first mod. Don't have high expectations, i made it mostly to train at modding but i've submitted it 'cause maybe someone on this planet would like it.
That's in override format, no .pdmod bullcrap, so just take the folder inside the .rar file and put it into your mod_overrides folder
Btw i made it sound a bit earrapey on purpose, i wanted REAL bass boost
