So now 

it’s

 time to get down to building your pedal! 

 
We are hoping to go from this        

             

                      to this   

 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
The first  thing you must do is identify your parts from the pack.   I suggest you separate them into 
groups of like components, working on one smaller group at a time.  
 
Start with the main PCB and set aside anything to do with the offboard section. You  won

’t

 need to 

worry about that bit for a while yet. 
 
As  a  rule,  I  build  from  small  to  big 

  therefore  step  one  will  be  to  identify  the  resistors  and  any 

diodes inside your kit.  
 
Each kit has a parts list at the top of the guide. So as an example, if R1 is listed as a 1M resistor then 
you dig out a 1M from the pack and place it on the PCB in the R1 spot. It

s your call if you put one in 

and solder or put a few in or even put them all in and solder. I’ll let you decide. 

 

 
The front of the PCB is the side with the white writing on (the silkscreen) 

 
 
 
You  then  need  to  follow  the  same  process 
for  all  the  other  parts.  Working  in  height 
order mount the rest of the parts to the PCB 
ensuring  that you solder them in  place  well 
as you go. 
 
I then add the pots either mounting them to 
the board or wiring them into place.
