Step 2 : Flip the PCB over so that the bottom or solder side is up. Insert the
four potentiometers, toggle switch and the LED into the bottom side of the
PCB.
If your pots have covers, remove them before continuing. You
might have to cut a slit in the cover with a blade and use a small
screwdriver to get leverage.
DO NOT SOLDER ANYTHING YET!!!
The LED will have one lead that is longer than the other. THIS WILL GO
INTO THE SQUARE SOLDER HOLE.
There are only two ways you can insert the toggle switch. Either way is
fine.
