You can find a guide for every product by visiting the shop page for that item. The wiring board offers many advantages over using just the foot switch. It uses a standard wiring scheme built in with additional options so you do not need to Star Ground etc…
Here is the link for the 3PDT Wiring Board Document:
Make sure you use the (T) pad on the main board In and Out. The other pad is a ground.
Make sure you put the finished build in the enclosure with loose pots before you solder them to the board. Those are two of the most common mistakes. It is better to fit the pots in the enclosure first and then the board before soldering them.
Also we suggest going to our guides section before building since all of our builds use the same scheme.
The CLR white pad is so you know the 2nd color of a Bicolor LED or “the OFF color”. If you only use a standard on/off LED you are not to use the white pad as it is only for a bi-color led. This is explained in the build document.
