Hi everyone! This is my first PCB that i've designed so far and i'd like to order it and see if it works.

Before that, i could use some guidance from someone more experienced than me, to let me know what i've done wrong and what i could improve.

The main goal of this project is to amplify or attenuate the low/high frequency of an audio signal.

Your capacitors are in the wrong polarity.

Place these capacitors close to the opamp.

And if C11 and C12 are ceramic, then your symbol is incorrect. If tantalum, you are missing the polarity data in the footprint.

i m going to order it from jlcpcb with some components already place. ive noticed that they dont have 100u cap with a higher voltage rating . would a 10 µF capacitor be enough to replace C11 and C12?

Yes
