  • Page 8 STEP 3 – 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. Capacitors (13) (electro) C3, C4, C7 (electro -...
  • Page 9 STEP 4 – LED and Battery Clip Solder wires Then, solder then to the LED (the red connection (red to the “+” sign). wire is connected to the longer pin). Solder the battery clip, connecting the red wire to the “+” sign:...
  • Page 10 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!):...
  • Page 11 STEP 6 – Audio Jacks Now, solder the audio jacks to the board (DC, battery and led wires are not present to make it clearer):...
  • Page 12 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).
  • Page 13 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.
  • Page 14 Then, solder them to the board like in the picture in the left, and then place the board inside the enclosure:...
  • Page 15 DOUBLE POTENTIOMETERS It’s the same as for single potentiometers, but you have to cut 6 pieces of wire for each one (i.e. 12 pieces for 2 potentiometers). Then, solder them to each lug. The first lug for each of the 2 gangs is the one in the left in top view (the black wire in the picture).
  • Page 16 Then, solder them to the board like in the pictures below:...
  • Page 17: Step 8 - Dc Power Jack

    STEP 8 – DC 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:...
  • Page 18 STEP 9 – 3PDT A – Solder the pin to the adapter B – Solder the 3PDT Pay attention, the pins and the 3PDT Now solder the 3PDT to the PCB and must be soldered to the same side of remove all the nuts but one, that should the PCB adapter (the one labeled be set at a middle height:...
  • Page 19 C – Solder the 3PDT directly to the board (optional) If you prefer to solder the 3PDT directly to the board, you can wire it as shown in the schematic. We recommend to use the provided 3PDT PCB adapter to make the soldering easier.
  • Page 20 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!
