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
-
P3
are PCB mounted potentiometers (Alpha). The rectangle pad marks pin 1 of a
potentiometer. NB the pots need to be soldered ont the bottom side not the component side
(top side). The image to the left shows 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 PCB mounted SPDT (on-on) switch or you can use a switch
with solder lugs for external use.
Place the potentiometers in the predrilled enclosure and then insert the PCB.
Once the PCB fits nicely and is not touching the enclosure, solder the
potentiometers to the PCB. Now you will need to wire the footswitch, LED
and DC jack:

Tip
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:
