Build sequence 

 

Before you start, you must decide which version you are going to build!  
Soldering this board can be very complicated for some people since the solder pads are close 
together. Use a magnifying glass to make the job easier.  

The trick to soldering a PCB is to work from small to big components. My building sequence 
suggestions in this section are based on the parts I used myself. Sometimes some components are 
smaller (or bigger) so always use your own common sense and change the order accordingly. Usually 
capacitors can differ a lot in size depending on their rating and value. 

Note: Do not blow on your solder in an attempt to cool it down. That can result in a bad join that 
might corrode! Also take extra care not to short components. 

Start by soldering the resistors and then the diode. Next, solder the IC socket for IC1 and then the 
MLCC capacitor. Finish by soldering the MKT/SMF/Wima capacitors and then the electrolytic 
capacitors. See the off board wiring section for details about the potentiometers and how to wire 
them. 

You are almost ready to rock, well… not really. The difficult part starts now.  

Besides the components mentioned in the components table, you will need: 

 

1 mono input jack  and 1 stereo input jack.  

 

3PDT footswitch (9 pins)  

 

2,1mm DC jack (isolated) not recommended in positive ground setup.  

 

22 gage stranded hook-up wire. 

 

OPTIONAL LED holder and LED (3mm or 5mm depending on your taste).  

 

Hammond 1590A case (or similar) in your favorite color. If you need more room you could 
consider using a Hammond 1590B
