FOOTSWITCH PCB
Next, it’s time to finish up the footswitch board. You should have done most of the on-board components
on this board in a previous step, but if not, go back and do those.
It’s easiest to start with the slide switch. Fit it in as shown in the diagram above, with the slide lever
facing to the right. Be careful—the pads are small. Make sure you don’t accidentally “bridge” two pads
together when soldering or you will have issues with the bypass.
The wires are next. There will be one longer assembly with 4 wires and two shorter ones with 3
wires. The longer one goes in the middle and the shorter ones go on the left and right sides. The wire
assemblies should then be soldered to the footswitch board as shown.
Once all three wire assemblies are soldered, set the footswitch PCB aside. We’ll solder the actual
footswitch and LED in a later step.

STEP 3
Then, solder the wires from the top.
This is the trickiest part of the whole
build. You want to solder the pads
without touching the iron to the
wires themselves and risking burning
through the insulation. It helps to
use a sharp or narrow tip on the
soldering iron.
STEP 2
Next, bend the wires back upward
and fit the ends of the wires into the
solder pads.
On the top side of the PCB, bend the
exposed wires backward so it holds
the wire in place. Pull the header
back up through the slot partway.
STEP 1
First, thread the wire through the
strain-relief slots, with the blue side
facing outward.
For now, pull it through as far as it
can go.
