Now put all the switches in place but don't solder it yet. Insert the acrylic front panel letting the
potentiometers and switches pass through the holes. Screw all the switches and solder it. Note
that the pots will not use the nuts.
The last components that we solder to the PCB are the leds. Insert the leds through the holes. The
leds are polarized. The short leg goes where the circle is cutted on the footprint. Insert the panel
again and insert the leds through its own hole. Solder it now.
