STEP BY STEP GUIDE

STEP 1 –Resistors and diodes
Place the resistors and diodes. If you have
troubles reading the values, check out our
“Reading Part Values” tutorial.

STEP 2 –Capacitors and Transistors
Solder the capacitors and transistors. If you have
troubles reading the values, check out our
“Reading Part Values” tutorial. Pay attention to the
orientation, as well as to the polarity for
electrolytic capacitors.

STEP 3 –Pin header
Connect the 6 pin header:

STEP 4 –LED and Battery Clip
Solder two wires to the LED
connection (red to the “+” sign).
Then, solder then to the LED (the red
wire is connected to the longer pin).
Solder the battery clip, connecting the red wire to the “+” sign:

STEP 5 –DC Power Jack wires
Solder three wires (about 5cm each) to the DC connection as shown (don’t solder
anything to the other end yet!):

STEP 6 –Audio Jacks
Now, solder the audio jacks to the board (DC, battery and led
wires are not present to make it clearer):

STEP 7 –Potentiometers
A – Preparing the potentiometers
Cut 3 pieces of wire for each potentiometer you have to solder (i.e. 9 pieces for 3
potentiometers). Then, solder them to each lug. The first lug is the one in the left in
top view (the black wire in the picture).
Here, we’ve cut them short (~1cm), but you can use the length you need.

The pin 1 is shown in the PCB, either as a dot or as a “1” number (left picture). If your
board doesn’t specify a “1” or a dot, then the default 1 pins are being used. Below you
can find the default pin 1 for our PCBs.
You can solder the potentiometers from above or from below (which we prefer)
depending on how you plan to build the pedal.

Then, solder them to the board like in the picture in the left, and then place the board
inside the enclosure:

STEP 8 –C Power Jack
First of all, insert the DC jack in the enclosure and tighten the
nut:
Then, solder the three wires from the DC connector in the
board to the DC jack as follows:

STEP 9 –3PDT
A – Solder the pin to the adapter
Pay attention, the pins and the 3PDT
must be soldered to the same side of
the PCB adapter (the one labeled
“buttons and 3PDT on this side”).
B – Solder the 3PDT
Now solder the 3PDT to the PCB and
remove all the nuts but one, that should
be set at a middle height:

STEP 10 –Connect the 3PDT
STEP 11 –Your pedal is finished!
By now you should have a fully functional effect pedal, we
hope you enjoy it!
