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 3: Full Schematic
Full Schematic This schematic includes optional components which won’t be used on every build. SW1+2, along with D8, D9, D3 and D6 are only used if you wish to include clipping options. If you aren’t doing this just add jumpers as shown in blue below. - Page 4 Notes THAT SCOOPED MID-RANGE The power and signal pads on the PCB conform to the FuzzDog Direct Connection - NO THANKS! format, so can be paired with the The Big Fluff Pie has a distinctive scooped appropriate daughterboard for quick and mid-range.
- Page 5 Notes CLIPPING SWITCHES ALTERNATIVE TONE SECTION There are pads to add extra clipping diodes if We’ve incorporated parts so you can easily you want some variation in your pedal. modify the tone stack and add a mids control. We’ve stuck to the simple elegance SW1 is for the first clipping section, and of the AMZ Presence Control.

- Page 8 Csnd Supa Tonebender 100K ‘73 UK interpretation. The first clipping stage is removed which 470K changes the sound to a mix of Tonebender-meets-Fluff. Heavy! 100R Transistor pinout is reversed so flip them. There was an extra cap between the third gain stage and the tone section, but it’ll sound 820R just the same without it.
- Page 9 Hooowwf (+Cloven variation) 100K Nice example of slight modifications to a BFP making a BIG difference to the 470K tone. The germanium cans and LED clipping make this a crunchier, grittier 100R experience - worth checking out even if you already have a BFP. Experiment with NPN Ge cans in Q3-4.
- Page 10 B&M Champion Fuzz Unit Another vintage British interpretation, pretty much identical to the Jumbo Tonebender. BC184C may be hard to come by, so try others. Looking for around 600hFE in Q1 and Q2, 150hFE in Q3. 100K 100n 470K 470p 100R 100n 100n...

- Page 12 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.
- Page 13 Wire it up (if using a daughterboard please refer to the relevant document) BOARD BOARD INPUT BOARD BOARD BOARD BOARD BOARD BOARD BATTERY Wiring shown above will disconnect the battery when you remove the jack plug from the input, and also when a DC plug is inserted. The Board GND connections don’t all have to directly attach to the board.
- Page 14 Wire it up - keep it neat There are pads on the main PCB to facilitate easy wiring for top-mounted jacks and DC. You can use the DC connections whether you’re connecting the main PCB and daughterboard with 4 or 6 way connectors. If you want to use the main PCB jack connections you should use a 6-way connector (or just 6 wires if you don’t like ribbons) to connect the two PCBs.

Wiggle room = good! If you want to top-mount your jacks you’ll have to move the pots/toggles down a bit, and how much depends on which jacks you use.
