Modifications 

Boost (foot)switch 

On the original pedal 

SW1

 only has 2 boost positions (on and off). On this PCB 

SW1

 is by default a 

3PDT (On-Off-On) switch soldered on the PCB and so giving you 3 options: High boost, no boost and a 
custom boost. As you can see left and middle position are as in the original (on and off). The right 
position enables you to create a custom boost level determined by 

R11

 and 

R24

. By default

 

these are 

6k8 resistors, creating a 2/3 level boost. You can change these values in the range between 6k8 and 
15k. 15k will create ½ level boost. 
 
If you only want 2 boost options as in the original, then leave out 

R11

R24 

and use a standard DPDT 

(On-On) for 

SW1

 

SW1

 can also be foot switchable. For this leave out 

R11

 and 

R24

 and use a standard 3PDT footswitch. 

To make it a bit easier, there are 3 special pads attached to 

SW1

 on the PCB: 

 

 

 
Remember that all 3 middle lugs on the switch must be soldered together by that single wire! As 
there is only one LED+ pad, you can solder the Anode of the LED directly to the + side of the DC jack 
as depicted above.
