The other way you could hook up the footswitch would involve manual wiring. This is a method that
can be used on any pedal. The following image gives a good visual representation of how to hook up
the entire pedal, albeit in a different enclosure.
To compare this to the earlier 3PDT image that had numbers on
the pins, you would have this…

There are loads of other ways to wire up a foot switch, the two ways I suggest are simple and
effective.
A CLR is a current limiting resistor. It reduces the voltage hitting the LED. On this picture the CLR is
shown as 2k2. We supply 4k7 but you can use any value up to around 10k.
Just like we did at the test phase all your ground points must connect, there are usually 5.
•
The main PCB has a ground plane and a couple of pads marked G. You can use both, or just
one.
•
The power supply has a ground lug, you should have a black wire on it from earlier.
•
Both jacks have a sleeve which needs to connect to ground.
•
The footswitch has a ground lug.
The same goes for all V pads. V is the direct power feed. So you must connect power to the CLR and
to the V pad on the main PCB
Please make sure you
get the switch lugs the
correct way!
