i built one years ago with my own etched pcb and, IMO, it sounds a lot better. i'd like to make this new pedalpcb version sound more like it. i'll have to see if i used the same component values in it, so i think that i'll have to mod it.Is this a troubleshooting thread or are you asking for modifications to fix it? So the tone control does something, but it's just too dark?
just continuity checked it and it's soldered fine.Check out r11. It looks like one end isn't soldered properly.
