I have ridden this pedal but unfortunately it really sizzles! and the more you give the resistor R3 sustains more than he loses. I have seen pictures of that pinnacle generally use trimpot someone has to provide a layout?? because it must have some prooblema.

In these last days I have made many tests on this plan. They are finally successful to stabilize FX and to find the just compromise for optimization with use of jfet J201. Nothing buzz, nothing hiss, nothing oscillations and feedback, only great sound.

I made some modification in any value of component.Now the sound is better, more round and fat and less acid.
Thanks for your attention and good job.
Here the layout with the new values.
