The power and signal pads on the PCB conform to the FuzzDog Direct Connection format, so can be paired with the appropriate daughterboard for quick and easy offboard wiring. Be very careful when soldering the LED, transistors and diodes. They’re very sensitive to heat.

Test the board! BATTERY 9V GND Your nice, new circuit board INCLUDING WIRED POTS!!!! 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.

Wire it up - with battery (if using a daughterboard please refer to the relevant document) BOARD BOARD INPUT BOARD BOARD BOARD BOARD LED+ BOARD BOARD BATTERY This circuit is standard, Negative GND. Your power supply should be Tip Negative / Sleeve Positive. That’s the same as your standard pedals (Boss etc), and you can safely daisy-chain your supply to this pedal.
