Build sequence
Soldering this board can be very complicated for some people since the solder pads are very 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 diodes. Socket the IC’s . Wait with placing the IC’s to once you are
finished with all soldering and off board wiring!
Now continue by soldering the MLCC, SMF and MKT capacitors and finish with soldering the the
Electrolytics.
I suggest you now drill the holes in your enclosure so you can use it during the off board wiring.
Note: Really take some time to determine where to place the pot, switch, jacks and PCB in the
enclosure before you start drilling. Measure twice, drill once.
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, 1 stereo jack, or 2 mono jacks if you are not planning on using a battery
3PDT footswitch (9 pins)
2,1mm DC jack (isolated).
22 gage stranded hook-up wire.
LED holders. This enables you to mount the LEDs in the enclosure.
LED (3mm or 5mm depending on your taste). These are the status LEDs
Hammond 1590B case (or similar) in your favorite color.

Off board wiring
Potentiometers
In the pictures below you see the correct pin numbering of the pots (Alpha 16mm style).
Solder the wires accordingly and it is always a good idea to twist the wires together to create some
extra shielding against external noise. The rectangle pad marks the pad for pin 1.
You can break off the pin I marked with the yellow circle with a small pair of pliers.

Note that R led1 is 4k7 resistors. You can change these value depending on the type of LED you use
but 4k7 is safe enough for almost all LEDs @9V.

Troubleshooting
All PCB’s have been 100% factory e-tested and out of every batch I receive I build an effect to double
check, so there should not be a connection problem on the PCB itself.
The board is not working (at all), what now?
Check if your 9V is plugged in correctly (and/or soldered correctly on the board). Pay special
attention to the polarity.
Check that you oriented the capacitors, IC’s ,transistors and diodes the right way. SMF, MKT
and ceramic capacitors as well as resistors do not need to be oriented. A likely sign of
incorrect capacitors and/or orientation is when an effect is sputtering, rumbling or
“motorboating”.
Check if you used the correct values of the components. For resistors you can look here:
http://www.diyaudioandvideo.com/Electronics/Color/
Double and triple check your soldering! A loose or cold solder can be really bad for your
board.
Replace the IC and/or transistors, one might be defective. Before doing that first unplug the
9V and wait for 5 seconds.
Check that you have good/high grade components. A lot of Chinese sourced parts are fakes
(especially high end opamps, audio capacitors, vintage diodes and transistors) so be careful
that you source your parts from reliable suppliers.
