First we start with the bare pcb and insert the first parts.
Sometimes the marking on the silkscreen isn’t very good to see.
Luckily the land has different shapes. The Cathode (the side with marking) comes in the hole with the square land. (see picture above)
Now use a piece of wire (e.g. one from the 1N4148 diode) and put it in the place named “JUMP”. If you are using a very bad noisy power supply you can replace the wire with a small value resistor (like 100 Ohm). The resistor in conjunction with the 10µF caps will result in a low pass filter for the power rail. It kind of “isolates” the audio-path of the effect from the rest of the circuit. Usually this step isn’t needed at all! If you consider to insert a resistor in instead of the wire. Please contact us first.
