Step 2

: Flip the PCB over so that the bottom or solder side is up. Insert the A100k

(LEVEL) and C500k (GAIN) potentiometers, and the LED into the bottom side of the
PCB.

DO NOT SOLDER ANYTHING YET!!!

The LED will have one lead that is

longer than the other.

MAKE SURE THE LONGER LEAD GOES IN THE SQUARE

HOLE.
