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.

The power and signal pads on the PCB conform There are extra pads on trimmers to allow to the FuzzDog Direct Connection format, so can different package formats to be used. Pads are be paired with the appropriate daughterboard for connected via PCB traces as shown above, so quick and easy offboard wiring.

Transistor orientation You can use transistors with any combination of pinouts. TO-18 transistors should follow the screen print, with the emitter tab as shown. Standard EBC transistors, such as 2N3904, 2N5088 Standard EBC transistors, such as 2N3904, 2N5088 Standard EBC transistors, such as 2N3904, 2N5088 Standard EBC transistors, such as 2N3904, 2N5088 Standard EBC transistors, such as 2N3904, 2N5088 Standard EBC transistors, such as 2N3904, 2N5088...

Test the board! Check the relevant daughterboard document for more info before you undertake this stage. UNDER NO CIRCUMSTANCES will troubleshooting help be offered if you have skipped this stage. No exceptions. Once you’ve finished the circuit it makes sense to test is before starting on the switch and LED wiring.
