When you get to the stage with the board and pots wired you need to test the board before you add
the foot switch.
Firstly, don’t put it in the box –
I see people building inside a tiny enclosure and I
wonder why. Some PCB’s are tight enough as it is without reducing your workspace to 6
cm wide!
Connect Input pad to TIP of Input jack. Same with output. Then connect the power to the 9v pad.
Connect all grounds together (board, jack sleeves and 9v) If your board is working at this point then
you can start work on the switch! If not…get double checking! If you email asking me why your pedal
isn’t working the first thing I
will ask is…
“
did it work without the switch?
”, s
o make sure you follow
this step.
If your PCB is working you are ready to connect the board to the footswitch! Follow the next stages
meticulously and all being well by the end of it you will have a lovely finished pedal!
The next step involves undoing the tip wires from the PCB as they will now move to the 3PDT.
If its not working at this stage then you need to find out why. Do not continue beyond this point until
you get it working. Adding a footswitch will not magically make a circuit work.
Troubleshooting is a necessary evil at times.
The Footswitch.
Have a look at the footswitch. It has 9 pins. The orientation of the switch is crucial. If you do it wrong
your switch will not work, you might ruin it and you will certainly have to un do it.
To help you a little further with ensuring the orientation of your switch is correct. To compare both
3PDT images you would have this…
Pin 1
–
Empty
Pin 2
–
Ground
Pin 3
–
LED
Pin 4
–
Pin 7
Pin 5
–
Input Jack tip
Pin 6
–
PCB Input
Pin 7
–
Pin 4
Pin 8
–
Output Jack Tip
Pin 9
–
PCB Output
Please make sure you
get the switch the
correct way!
The pins on the switch must run left to
right like this, so the top row of pins would
be 1, 4, and 7.
If you put it in with 1, 2, and 3 across the
top row you are wrong.
