There seems to be no standard for gate voltage in Eurorock.
Generally 5v but can be up to 12v.
Modules usually have a threshold of 2v, and standard input impedance is 100k ohm. In some cases they need a sharp attack in order to trigger.
In this circuit -12v is unused. Current is around 2mA max, when output shorted. Diode is used to represent a diode which exists in some footswitches, not part of circuit, since addition of debounce this prevents a sharp attack. Just leave it out.
The 10k resistor on the collector of the second transistor can be used to modify gate voltage.
100n capacitor de-bounces the switch. In the real world circuit 1u was used.
Transistors 2n5551, not accurately modelled.
Diode does not illuminate on model. Does in real life. It's a 3mm orange device, cheap from Aliexpress. Rated at 20mA, but bright enough with 6k8 resistor.
