Hi everyone!
What's the internal trimpot for? Can anyone tell me how to adjust it properly? I'm finishing this build.
Thanks in advance.

The internal control is to adjust the sensitivity of the optocouplers. IIRC i set everything kind of flat and then adjust the internal control to get the best whacka sound.

Ok great, and thanks for the reply...

One more question:
This board takes two on-on-on switches. On the internet there are 2 types of on-on-on switches; appropriately named, "type 1" and "type 2". Lol! Do you know which one does this board, and for that matter, all effects boards use? I attached a gif of the 2 types...
Thanks again for your help.

Ok, thanks again. I will order those.

Thanks for the links. Luckily, what I did was to select two nsl32s that had similar resistances vs led brightness. And yes, the optos are really vary from unit to unit. I'm hoping this will make the pedal work as it should
