It should look just like this 
 
The next thing to do is to plug it in. Hopefully its obvious that it needs some power and a decent 
power supply is what is called for, the cheap £6.99 ones are not good. 
 
Guitar (or whatever you play) goes to the input jack and then the output jack goes to your amp. Set 

the controls to half way up and…. Play.

 

 
Hopefully its alive and 

kicking.  If it’s not working, then you need to find out why. Do not continue 

beyond this point until you get it working. Adding a footswitch will not magically make a circuit work. 
Troubleshooting is a necessary evil at times.  
 
The best advice now is to have a quick break. Fresh eyes spot faults an excited mind missed! Once 
you have had a break take some good quality photos and upload them to the 

forum

 for some peer 

support. 
 
 
If your PCB is working you are ready to connect the board to the footswitch! Follow the next stages 
meticulously and all being well by the end of it you will have a lovely finished pedal!
