Step 13: Final wire-up
With all of the components in place, it is time to wire it all up.
Starting on the left-hand side of the circuit board, wire up the
DC jack first. The wire labeled V+ connects to the +9V lug.
V- connects to Masse (GND) lug. B+ connects to B lug.
Next solder the input jack. Solder the wire labeled B- to the
lug that connects to the shorter tip of input jack. This will
disconnect the battery when unplugged. Next solder the
wire labeled G to the sleeve lug on the input jack. This lug
connects to the threaded shaft of the jack.
Continuing, solder the wire labeled I to lug #1 on the foot-
switch. Solder the wire labeled O to lug #4. Finally, solder
the wire labeled G to lug #7.
Solder the final wire labeled L to the positive (long) lead of
the LED.
Moving on to the footswitch, solder a wire to lug #2 then
solder the same wire to the lug of the input jack that con-
nects to the longer tip. Solder the wire with the 1/4” striped
end to jumper lugs #3 and #5 on the footswitch, then solder
the same wire to the tip lug of the output jack. Finally solder
the negative (shorter) lead of the LED to the #8 lug of the
footswitch.
Add a battery, if you would like. Screw on the back panel
and plug in!
The lugs on the footswitches are
numbered as shown above.
The lugs on the DC jack are as
show above.
