I looked through all your threads and posts looking tor the 3.3uF capacitor that I recommended from 220nF and found it in your different thread over 1 year ago. It is C28 to ground which is in series with the 1k R46 at pin 2. 3.3uF passes most audio frequencies.
When C28 is 220nF it cuts 727Hz and all lower frequencies like in the TS-808 screamer circuit and in a You Tube distorted guitar video.
The gain control affects how much distortion you have, maybe it is wired incorrectly.
Here are a couple of schematics:
