13. Potentiometers (VR1 - VR9): Install the control pots. You will manipulate these components
more than any other, so be careful to seat them securely against the PCB (57,58). Solder them
carefully and securely (59). Do not use too much heat. If you cannot move quickly with your iron,
place all nine pots in the board and solder one pin on each pot sequentially. This will allow each
pot to cool before you solder its next leg (60).
