Boss metal zone snoring

[Paulo Shure]

First of all I would like to apologize for my faulty English'm using the translator. I made a change in my metalzone where I put a key switching capacitor c36 which was to change the equalizer range put the original (223) at one end and a 1uf the other when it selected the original pedal snores when move the knobs will have to change some more component to be normal?
