Yes, D3 "goes the other way".

thanks cctsim,
i guessed right. i put a led in series with d3 to make it a little late clipping so it won't be so "compressed" i might totally remove the in4148 in d3 and just have the led there. i'm trying to lower the drive in the od section, just like what you get when you have an od with low gain boosting a ds-1 with higher gain.

You can also reduce the AC gain of the two treble boosters before the OD stage.
To do that try to change C10 and C14 to 470 pF or even 1 nF.
You can also reduce R20 to 100k.
Do one change at the time though. |
