  • Page 2: Important Notes

    Important notes If you’re using any of our footswitch daughterboards, DOWNLOAD THE DAUGHTERBOARD DOCUMENT • Download and read the appropriate build document for the daughterboard as well as this one BEFORE you start. • DO NOT solder the supplied Current Limiting Resistor (CLR) to the main circuit board even if there is a place for it.

  • Page 5 The power and signal pads on the PCB conform Be very careful when soldering the diode, to the FuzzDog Direct Connection format, so can transistors and LEDs. They’re very sensitive to be paired with the appropriate daughterboard for heat. You should use some kind of heat sink quick and easy offboard wiring.
  • Page 6: Toggle Switches

    Toggle Switches If you aren’t using some of the toggle switches you need to place jumpers instead. ORDER SWITCHER Place jumpers from the centre pads to the lower pads as shown in red above. This will give you the standard format of right hand fuzz circuit (Soda) into left hand drive circuit (Ripper). If you’re really strange you can reverse that order by connecting the centre pads to the upper pads instead.
  • Page 7 JOINING THE BOARDS Connect the two footswitch daughterboards to the main PCB with wires or ribbon cables. Ensure the pads correspond, i.e. don’t get the switch boards upside down! Don’t forget the current limiting resistors (CLRs) for the LEDs. The fit vertically in the two pads marked CLR on the daughterboards, same side as the footswitches.
