12. Follow these steps:
    A. Bend the pins of the 3mm white LED as shown in the pictures below.
    
    
    B. Cut a 7mm piece of 2.4mm shrink tube.
    
    C. Slide both the 3 mm white LED and the 3 mm photo transistor in the shrink tube as shown below. No need to actually shrink the tube. This will act as the lightbridge.

16. 5 mm blue LED: LD1 (do a diode test with a multimeter to find the blue LED)
    Note the polarity!
    Make sure it stands out about 12 mm from the PcB, as shown in the picture!
    
    

17. 5 mm white LED: LD3 (do a diode test with a multimeter to find the white LED)
    Note the polarity!
    Make sure it stands out about 12 mm from the PcB, as shown in the picture!
    
    Turn the PcB around!

18. capacitor 220 µF: C2
    Note the polarity!
    Solder on the bottom side of the PcB!
    

19. capacitor 10 µF: C5, C7, C8, C12
    Note the polarity!
    Solder on the bottom side of the PcB!
    

20. capacitor 47 µF: C10
    Note the polarity!
    Solder on the bottom side of the PcB!
    

21. capacitor 100 µF: C13
    Note the polarity!
    Solder on the bottom side of the PcB!
    

22. Trim the leads on the 9 V snapt to 5 cm.
    
    Strip and tin both wires
    

23. Place and solder the 9 V snap to the PCB as shown in the images below.
    Note the polarity! RED = +, BLAcK = –
    
    
    
    
    Slide 4,5 cm of the biggest shrink tube over the connector. When no battery is used in the pedal this cover should always be used.

26. Install the footswitch as shown in the images below.
    
    
    

27. Install the selector switch as shown in the images below

28. Install the 2 potentiometers as shown in the images below. Note the placement of the different values!
    
    

29. Trim the leads of the 6 wire female connector to 4.5 cm.
    

30. Strip and tin the wires
    

31. Cut 6 x 7 mm pieces of the 2.4 mm shrink tube.
    

32. Solder the wires to the footswitch as shown below. Do not forget the shrink tube pieces and note the colors.
    
    
    

33. Trim the leads of the 2 wire female connector to 4.5 cm.
    

34. Strip and tin the wires.
    

35. Cut 2 x 7 mm pieces of the 2.4 mm shrink tube.
