Off board wiring
The biggest challenge of this build is to get all the offboard wiring correct and fit it in a box. Take your
time measuring and testing before you start fitting everything in the box.
P1
-
P4
are PCB mounted potentiometers (Alpha). The rectangle pad marks pin 1 of a potentiometer.
The images below show how you can recognize which pin is which on a potentiometer. You can
break off the pin I marked with the
yellow circle
with a small pair of pliers.
SW1
is a regular DP3T (on-off-on) switch with solderlugs and
SW2
is a PCB
mount version SPDT switch.
Place the potentiometers and switches in the predrilled enclosure and then
insert the PCB. Once the PCB fits nicely and is not touching the enclosure, solder
the potentiometers and switches to the PCB.
Now you will need to wire the footswitch, LED and DC jack:
The LED requires a resistor (R led in the diagram) depending on the type of LED you are using. An
ultra-bright red, green or blue LED requires a 4k7 resistor, diffuse green requires 680R. If you want to
be more exact then go here:
