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.

Schematic Alterations have been made to the output stage of the op amp circuit to increase volume as the 680K original was a bit lacking. Thanks to Plesur and 680K his Feta Complis document for those details. 470R 100K 100K 470K Q1-3 2N3904...

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 diodes, LED and transistors. They’re very sensitive to heat.
Hack alert! If your PCB is marked as V1.1 this hack is not necessary. Solder the transistors as normal. A small hack is required to get this working. Bend the middle leg of Q2 out to the front before placing the two outer pins in their pads.

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.

Wire it up - DC only version (if using a daughterboard please refer to the relevant document) BOARD BOARD INPUT BOARD BOARD BOARD BOARD LED+ BOARD BOARD 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.

BOARD BOARD BOARD LED+ BOARD Just because the BOARD FuzzDog enclosure BATTERY won’t take a battery, there’s nothing stopping you using a bigger box. 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.
