STEP 3:
THE POTENTIOMETER AND
PREVENTATIVE MAINTENANCE
Install the potentiometer that’s connected to
the circuit board and screw the knob to the
shaft. Use this time to check the traces on the
stripboard for continuity using a multimeter.
Put the multimeter in the mode signified with
the sound wave and test adjacent traces.
If they beep, then there is a solder bridge
and they need to be cleaned up. Also, check
continuity across the cuts you made in the
board earlier. If your potentiometer has
a dust jacket, feel free to leave the board
floating. If there is no dust jacket, consider
securing the board to the back of the pot
with some double-sided mounting tape.
STEP 4: INPUT AND OUTPUT
Connect the input and output jacks to the
footswitch as shown.
STEP 5: DC JACK
Connect the 9v- wire to the sleeve of the
input jack, then connect sleeve of the input
jack to the DC jack. On the DC jack, there
are three terminals. Two look alike, and
one looks different. You will be wiring the
sleeve lug to the different lug. Wire this
“different” lug to the corresponding lug on
the footswitch. Then wire the positive leg of
the LED and the 9v+ wire to BOTH identical
lugs on the DC jack.
STEP 6: FINISHING UP
Connect the “board input” and “board output”
wires to the correct lugs on the switch.
